In an embodiment, the energy management platform can be implemented as a software-as-a-service (SaaS) solution hosted in the cloud. The energy management platform may provide analytical applications for energy management that are built on a robust architecture.
The energy management platform in accordance with embodiments of the invention provides myriad benefits. In an embodiment, as a SaaS implementation, users of the energy management platform do not have to purchase and maintain hardware or purchase and integrate disparate software packages, reducing upfront costs and the upfront resources required from IT resources, such as an IT team or outside consultants. The energy management platform can be delivered “out-of-the-box”, reducing the need to define and produce precise and detailed requirements. The energy management platform may leverage industry best practices and leading capabilities for data integration, which reduces the time required to connect to required data sources. Software maintenance updates and software upgrades may be “pushed” to users of the energy management platform automatically, thereby ensuring that software updates are available to users as quickly as possible.
The energy management platform in accordance with embodiments of the invention provides various capabilities and advantages for an enterprise. Smart meter investment can be leveraged to derive accurate predictive models of building energy performance throughout a region of interest. Energy data can be compiled and aggregated into consolidated and consistent views of building performance across the region. Energy usage can be modeled and forecasted across some or all of the buildings in the region. The energy performance of buildings can be benchmarked against industry standards as well as internal benchmarks of the enterprise. The energy performance of buildings can be compared to identify low-performing outliers for potential energy improvements. The effectiveness of energy improvements can be tracked, measured, and quantified to identify those that provide the highest impact and greatest return on investment. The allocation of the costs and benefits of energy improvements among all stakeholders can be analyzed so that the enterprise, as well as broader constituents, can understand the return on its energy-related investments.

In an embodiment, each of the energy management platform 102, the external data sources 1041-n, and the enterprise 106 may be implemented as a computer system. The computer system may include one or more machines, each of which may be implemented as machine 600 of
The data management module 110 may support the capability to automatically and dynamically scale a network of computing resources for the energy management platform 102 according to demand on the energy management platform 102. The dynamic scaling supported by the data management module 110 may include the capability to provision additional computing resources (or nodes) to accommodate increasing computing demand. Likewise, the data management module 110 may include the capability to release computing resources to accommodate decreasing computing demand. The data management module 110 may include one or more action(s) 118, a queue 120, a dispatcher 122, a resource manager 124, and a cluster manager 126.
The actions 118 may represent the tasks that are to be performed in response to requests that are provided to the energy management platform 102. Each of the actions 118 may represent a unit of work to be performed by the applications servers 112. The actions 118 may be associated with data types and bound to engines (or modules). The requests may relate to any task supported by the energy management platform 102. For example, the request may relate to, for example, analytic processing, loading energy-related data, retrieving an energy star reading, retrieving benchmark data, etc. The actions 118 are provided to the action queue 120.
The action queue 120 may receive each of the actions 118. The action queue 120 may be a distributed task queue and represents work that is to be routed to an appropriate computing resource and then performed.
The dispatcher 122 may associate and hand-off a queued action to an engine that will execute the action. The dispatcher 122 may control routing of each queued action to a particular one of the applications servers 112 based on load balancing and other optimization considerations. The dispatcher 122 may receive an instruction from the resource manager 124 to provision new nodes when the current computing resources are at or above a threshold capacity. The dispatcher 122 also may receive an instruction from the resource manager to release nodes when the current computing resources are at or below a threshold capacity. The dispatcher 122 accordingly may instruct the cluster manager 126 to dynamically provision new nodes or release existing nodes based on demand for computing resources. The nodes may be computing nodes or storage nodes in connection with the applications servers 112, the relational databases 114, and the key/value stores 116.
The resource manager 124 may monitor the action queue 120. The resource manager 124 also may monitor the current load on the applications servers 112 to determine the availability of resources to execute the queued actions. Based on the monitoring, the resource manager may communicate, through the dispatcher 122, with the cluster manager 126 to request dynamic allocation and de-allocation of nodes.
The cluster manager 126 may be a distributed entity that manages all of the nodes of the applications servers 112. The cluster manager 126 may dynamically provision new nodes or release existing nodes based on demand for computing resources. The cluster manager 126 may implement a group membership services protocol. The cluster manager 126 also may perform a task monitoring function. The task monitoring function may involve tracking resource usage, such as CPU utilization, the amount of data read/written, storage size, etc.
The applications servers 112 may perform processes that manage or host analytic server execution, data requests, etc. The engines provided by the energy management platform 102, such as the engines that perform data services, batch processing, stream services, may be hosted within the applications servers 112. The engines are discussed in more detail herein.
In an embodiment, the applications servers 112 may be part of a computer cluster of a plurality of loosely or tightly connected computers that are coordinated to work as a system in performing the services and applications of the energy management platform 102. The nodes (e.g., servers) of the cluster may be connected to each other through fast local area networks (“LAN”), with each node running its own instance of an operating system. The applications servers 112 may be implemented as a computer cluster to improve performance and availability over that of a single computer, while typically being more cost-effective than single computers of comparable speed or availability. The applications servers 112 may be software, hardware, or a combination of both.
The relational databases 114 may maintain various data supporting the energy management platform 102. In an embodiment, non-time series data may be stored in the relational databases 114, as discussed in more detail herein.
The key/value stores 116 may maintain various data supporting the energy management platform 102. In an embodiment, time series data (e.g., meter readings, meter events, etc.) may be stored in the key/value store, as discussed in more detail herein. In an embodiment, the key/value stores 116 may be implemented with Apache Cassandra, an open source distributed database management system designed to handle large amounts of data across a multitude of commodity servers. In an embodiment, other database management systems for key/value stores may be used.
In an embodiment, one or more of the applications servers 112, the relational databases 114, and the key/value stores 116 may be implemented by the entity that owns, maintains, or controls the energy management platform 102.
In an embodiment, one or more of the applications servers 112, the relational databases 114, and the key/value stores 116 may be implemented by a third party that may provide a computing environment for lease to the entity that owns, maintains, or controls the energy management platform 102. In an embodiment, the applications servers 112, the relational databases 114, and the key/value stores 116 implemented by the third party may communicate with the energy management platform 102 through a network, such as the network 108.
The computing environment provided by the third party for the entity that owns, maintains, or controls the energy management platform 102 may be a cloud computing platform that allows the entity that owns, maintains, or controls the energy management platform 102 to rent virtual computers on which to run its own computer applications. Such applications may include, for example, the applications performed by the applications server 200, as discussed in more detail herein. In an embodiment, the computing environment may allow a scalable deployment of applications by providing a web service through which the entity that owns, maintains, or controls the energy management platform 102 can boot a virtual appliance used to create a virtual machine containing any software desired. In an embodiment, the entity that owns, maintains, or controls the energy management platform 102 may create, launch, and terminate server instances as needed, paying based on time usage time, data usage, or any combination of these or other factors. The ability to provision and release computing resources in this manner supports the ability of the energy management platform 102 to dynamically scale according to the demand on the energy management platform 102.
The analytics platform supported by the applications server 200 includes multiple services that each handles a specific data management or analysis capability. The services include the data integrator module 202, the integration services module 204, the data services module 206, the computational services module 208, the stream analytic services module 210, batch parallel processing analytic services module 212, and the UI services module 224. All or some services within the analytics platform may be modular and accordingly architected specifically to execute their respective capabilities for large data volumes and at high speed. The services may be optimized in software for high performance distributed computing over a computer cluster including the applications servers 112.
The modules and components of the applications server 200 in
The data integrator module 202 is a tool for automatically importing data maintained in software systems or databases of the external data sources 1041-n into the energy management platform 102. The imported data may be used for various applications of the energy management platform 102 or the application server 200. The data integrator module 202 accepts data from a broad range of data sources, including grid and operational systems such as MDM, CIS, and billing systems, as well as third-party data sources such as weather databases, building databases (e.g., Urban Planning Council database), third-party property management systems, and external benchmark databases. The imported data may include, for example, meter data (e.g., electricity consumption, water consumption, natural gas consumption) provided at minimum daily or other time intervals (e.g., 15-minute intervals), weather data (e.g., temperature, humidity) at daily or other time intervals (e.g., hourly intervals), building data (e.g., square footage, occupancy, age, building type, number of floors, air conditioned square footage), aggregation definitions (hierarchy) (e.g., meters to building, buildings to city block, building's regional identification), and asset data (e.g., number and type of HVAC assets, number and type of production units (for plants)).
The data integrator module 202 also has the ability to import information from flat files, such as Excel spreadsheets, and has the ability to capture information entered directly into an application of the energy management platform 102. By incorporating data from a broad array of sources, the application server 200 is capable of performing complex and detailed analyses, enabling greater business insights.
The data integrator module 202 provides a set of standardized canonical object definitions (standardized interface definitions) that can be used to load data into applications of the application server 200. The canonical objects of the data integrator module 202 may be based on current or emerging utility industry standards, such as the Common Information Model (CIM), Green Button, and Open Automatic Data Exchange, or on the specifications of the application server 200. The application server 200 may support these and other standards to ensure that a broad range of utility data sources will be able to connect easily to the energy management platform 102.
Canonical objects may include, for example:
Once the data in canonical form is received, the data integrator module 202 may transform the data into individual data entities in accordance with the data model 218 so that the data can be loaded into a database schema to be stored, processed, and analyzed.
The data integrator module 202 is capable of handling very high volumes of data (e.g., “big data”). For example, the data integrator module 202 may frequently process interval data from millions of digital meters. To receive data, the application server 200 may provide a consistent secured web service API (e.g., REST). Integration can be carried out in an asynchronous batch or real-time mode. The data integrator module 202 may incorporate real-time and batch data from, for example, utility customer systems, building characteristic systems, industry-standard benchmark systems, utility energy conservation measures and rebate databases, utility enterprise systems, MDM, and utility operational systems. When an external data source does not possess an API or computerized means by which to extract data, the application server 200 can pull data directly from a web page associated with the external data source (e.g., by using web scraping).
The data integrator module 202 also may perform initial data validation. The data integrator module 202 may examine the structure of the incoming data to ensure that required fields are present and that the data is of the right data type. For example, the data integrator module 202 may recognize when the format of the provided data does not match the expected format (e.g., a number value is erroneously provided as text), prevents the mismatched data from being loaded, and logs the issue for review and investigation. In this way, the data integrator module 202 may serve as a first line of defense in ensuring that incoming data meets the requirements for accurate analysis.
The integration services module 204 serves as a second layer of data validation or proofing, ensuring that data is error-free before it is loaded into a database or store. The integration services module 204 receives data from the data integrator module 202, monitors the data as it flows in, performs a second round of data checks, and passes data to the data services module 206 to be stored.
The integration services module 204 may provide various data management functions. The integration services module 204 may perform duplicate handling. The integration services module 204 may identify instances of data duplication to ensure that analysis is accurately conducted on a singular data set. The integration services module 204 can be configured to process duplicates according to business requirements specified by a user (e.g., treating two duplicate records as the same or averaging duplicate records). This flexibility allows the application server 200 to conform to customer standards for data handling.
The integration services module 204 may perform data validation. The integration services module 204 can detect data gaps and data anomalies (e.g., statistical anomalies), identify outliers, and conduct referential integrity checks. Referential integrity checking ensures that data has the correct network of associations to enable analysis and aggregation, such as ensuring that loaded meter data is associated with a facility or, conversely, that facilities have associated meters. The integration services module 204 resolves data validation issues according to the business requirements specified by a user.
The integration services module 204 may perform data monitoring. The integration services module 204 can provide end-to-end visibility throughout the entire data loading process. Users can monitor a data integration process as it progresses from duplicate detection through to data storage. Such monitoring helps to ensure that data is loaded properly and is free of duplication and validation errors.
The data services module 206 is responsible for persisting (storing) large and increasing volumes of data, while also making data readily available for analytical calculations. The data services module 206 partitions data into relational and non-relational (key/value store) databases and also performs operations on stored data. These operations include creating, reading, updating, and deleting data. A data engine of the data services module 206 may persist data for stream processing. The data engine of the data services module 206 also may identify a data set to be processed in connection with a batch job for batch parallel processing.
The data services module 206 may perform data partitioning. The data services module 206 takes advantage of relational and non-relational data stores, such as the relational database 114 and the key/value store 116. By “partitioning” the data into two separate data stores, the relational database 114 and the key/value store 116, the application server 200 ensures that its applications can efficiently process and analyze the large volumes of data, such as interval data originating from meters and grid sensors. The data in the relational database 114 and the key/value store 116 is stored in accordance with the data model 218 of the energy management platform 102.
The relational database 114 is designed to manage structured and slow-changing data. Examples of such data include organization (e.g., customer) and facility data. Relational databases, like the relational database 114, are designed for random access updates.
The key/value store 116 is designed to manage very large volumes of interval (time-series) data, such as meter and grid sensor data. Key/value stores, like the key/value store 116, are designed for large streams of “append only” data that are read in a particular order. “Append only” refers to new data that is simply added to the end of an associated file. By using the dedicated key/value store 116 for interval data, the application server 200 ensures that this type of data is stored efficiently and can be accessed quickly.
The data services module 206 may perform distributed data management. The data services module 206 may include an event queue that schedules provision of notifications to perform stream processing and batch parallel processing. With respect to batch parallel processing, the scheduling may be based on rules that account for the availability of processing resources in an associated cluster in the energy management platform 102. As data volumes grow, the data services module 206 automatically adds nodes to the cluster to accommodate (e.g., store and process) the new data. As nodes are added, the data services module 206 automatically rebalances and partitions the data across all nodes, ensuring continued high performance and reliability.
The computational services module 208 is a library of analytical functions that are invoked by the stream analytic services module 210 and the batch parallel processing analytic services module 212 to perform business analyses. The functions can be executed individually or combined to form complex analyses. The services provided by the computational services module 208 may be modular (i.e., dedicated to a single task) so that the computational services module 208 can parallel process a large number of computations simultaneously and quickly, which allows for significant computational scalability.
The computational services module 208 also may leverage distributed processing to create even greater scalability. For example, if a user is interested in calculating the average annual electricity use for hundreds of thousands of meters, the energy management platform 102 is capable of rapidly responding by distributing the request across multiple servers.
The stream analytic services module 210 performs sophisticated analyses on real-time and near-real-time streams of data. A stream may represent, for example, a feed of high volume data from a meter, sub-meter, or grid sensor. In an embodiment, the stream may be a Supervisory Control and Data Acquisition (SCADA) feed of data. The stream analytic services module 210 may be invoked to analyze this data when the analysis needs to be conducted soon after the data is generated.
The stream analytic services module 210 may include a stream processor to convert the stream into data that is in accordance with the data model 218. The stream analytic services module 210 also may include stream processing logic, which can be provided by a user of the energy management platform 102. The stream processing logic may provide a calculated result that can be persisted and used for subsequent analysis. The stream processing logic also may provide an alert based on a calculated result. For example, a utility may want to receive alerts and on-the-fly analysis when there is an unexpected and significant drop or spike in load. This load variation could be caused by a malfunctioning piece of equipment or sudden damage to equipment, and could possibly represent great risk to the distribution system or an end customer. Data about the unexpected load change can be rapidly recognized, analyzed, and used to send the necessary alert. The stream processing logic also may provide, after processing the original stream, a new stream based on the processed original stream for another purpose or application of the energy management platform 102.
The stream analytic services module 210 may perform near real-time, continuous processing. Because processing by the stream analytic services module 210 occurs very quickly after the data arrives, time-sensitive, high priority analyses provided by the energy management platform 102 are relevant and actionable.
The stream analytic services module 210 may provide horizontal scalability. In order to manage large volumes of data simultaneously, processing by the stream analytic services module 210 can be distributed throughout a server cluster, a set of computers working together.
The stream analytic services module 210 may provide fault tolerance. Streams may be persisted. If a processing failure occurs on one node (e.g., a computer in a cluster), the workload will be distributed to other nodes within the cluster with no loss of data. A stream may be discarded after the processing performed on the stream is completed.
A non-limiting example is provided to illustrate performance of the stream analytic services module 210. Assume streams of recently generated electricity consumption and demand data. The streams may be provided to an event queue associated with the data services module 206. When the data arrives into the event queue, automatic analytic processes are triggered. Multiple analytic processes, or analyses, can be run upon the same data set. The analytic processes may be performed in parallel. Parallel processing on the same data set enables faster processing of multiple analyses. The outputs of these analytic processes may be alerts and calculations that are then stored in a database and made available to designated end users as analysis results. The analytic processes and processing tasks may be distributed across multiple servers that support the stream analytic services module 210. In this way, large data volumes can be rapidly processed by the stream analytic services module 210.
The batch parallel processing analytic services module 212 may perform a substantial portion of analysis required by users of the energy management platform 102. The batch parallel processing analytic services module 212 may analyze large data sets comprised of current and historical data to create reports and analyses, such as periodic Key Performance Indicator (KPI) reporting, historical electricity use analysis, forecasts, outlier analysis, energy efficiency project financial impact analysis, etc. In an embodiment, the batch parallel processing analytic services module 212 may be based on MapReduce, a programming model for processing large data sets and distributing computations on one or more clusters of computers. The batch parallel processing analytic services module 212 automatically performs the tasks of parallelization, fault-tolerance, and load balancing, thereby improving the performance and reliability of processing-intensive tasks.
A non-limiting example is provided to illustrate performance of the batch parallel processing analytic services module 212. As examples, a benchmark analysis of energy intensity, a summary of performance against key performance indicators, and an analysis of unbilled energy due to nontechnical losses could be jobs handled by the batch parallel processing analytic services module 212. When a batch processing job is invoked in the energy management platform 102, an input reader associated with the batch parallel processing analytic services module 212 breaks down the processing job into multiple smaller batches. This break down reduces the complexity and processing time of the job. Each batch is then handed to a worker process to perform its assigned task (e.g., a calculation or evaluation). The results are then “shuffled,” which refers to rearrangement of the data set so that the next set of worker processes can efficiently complete the calculation (or evaluation) and quickly write results to a database through an output writer.
The batch parallel processing analytic services module 212 can distribute worker processes across multiple servers. Such distributed processing is employed to fully utilize the computational power of the cluster and to ensure that calculations are completed quickly and efficiently. In this way, the batch parallel processing analytic services module 212 provides scalability and high performance.
The normalization module 214 may normalize meter data that is to be maintained in the key/value store 116. For example, normalization of meter data may involve filling in gaps in the data and addressing outliers in the data. For example, if meter data is expected at consistent intervals but data actually provided to the energy management platform 102 does not have meter data at certain intervals, the normalization module 214 may apply certain algorithms (e.g., interpolation) to provide the missing data. As another example, aberrational values of energy usage can be detected and addressed by the normalization module 214. In an embodiment, normalization performed by the normalization module 214 may be configurable. For example, the algorithms (e.g., linear, non-linear) used by the normalization module 214 may be specified by an administrator or a user of the energy management platform 102. Normalized data may be provided to the key/value store 116.
The analytics container 216 may perform analytic processing. The analytics container 216 may include a machine learning module (not shown) that implements one or more varieties of machine learning algorithms to enhance energy and smart grid analytics. In an embodiment, the machine learning module may perform a plurality of processing steps including prediction followed by feedback and learning.
In an embodiment, prediction may include feature extraction, classification, and ranking. With respect to extraction, analytic processing may be performed on meter datasets, event datasets or other datasets. The data sets may include information from grid and operational systems, such as MDM, CIS, and other types of data identified herein. The datasets may be used to identify signatures of theft, consumption, demand, or other features such as consumption on inactive meter, tamper events, drop in consumption, producer at night, etc. The datasets may be based on data maintained in the relational databases 114 and the key/value stores 116. With respect to classification, different features may be selectively merged or weighted, and elements may be grouped to generate a set of follow-up opportunities. With respect to ranking, resulting opportunities may be prioritized based on the preferences and business operations of the enterprise 106. In an embodiment, prediction may be performed by the energy management platform 102.
In an embodiment, feedback may involve investigation by the enterprise 106 (e.g., utility) resulting in empirical data regarding energy usage or smart grid operation or conditions. The results of investigation may allow for the provision by the enterprise 106 of feedback to the machine learning module to adjust learned detection parameters.
The UI services module 224 provides the graphical framework for all applications of the energy management platform 102. The UI services module provides visualization of analytical results so that end users may receive insights that are clear and actionable. After analyses are completed by the stream analytic services module 210 or the batch parallel processing analytic services module 212, they may be graphically rendered by the UI services module 224, provided to the appropriate application of the energy management platform 102, and ultimately presented on a computer system (e.g., machine) of the user. This delivers data insights to users in an intuitive and easy-to-understand format.
The UI services module 224 provides many features. The UI services module 224 may provide a library of chart types and a library of page layouts. All variations in chart types and page layouts are maintained by the UI services module 224. The UI services module 224 also may provide page layout customization. Users, such as administrators, can add, rename, and group fields. For example, the energy management platform 102 allows a utility administrator to group energy intensity, energy consumption, and energy demand together on a page for easier viewing. The UI services module 224 may provide role-based access controls. Administrators can determine which parts of the application will be visible to certain types of users. Using these features, the UI services module 224 ensures that end users enjoy a consistent visual experience, have access to capabilities and data relevant to their roles, and can interact with charts and reports delivering clear business insights.
At block 312, the computational services module 208 performs post-processing on the first types of data. The stored first types of data may be post-processed to derive any kind of information that may be requested by an application of the energy management platform 102. Post-processing may include, for example, aggregate calculations and performance denormalization performed on the stored first types of data. Aggregate calculations may include, for example, summing periodic energy expenditures (e.g., monthly bills) into a total figure (e.g., annual amounts). Performance denormalization may include, for example, processing of the stored first types of data to optimize query performance. Other types of post-processing are possible. At block 314, the relational database 114 stores the post-processed first types of data.
For second types of data, the process 300 proceeds from block 306 to block 316. At block 316, the data services module 206 provides the second types of data to the key/value store 116. One example type of the second types of data is “raw” meter data relating to energy usage. Other examples of data stored in the key/value store 116 may include meter readings, meter events, weather measurements such as temperature, relative humidity, dew point, downward infrared irradiance, and asset state changes. At block 318, the key/value store 116 stores the second types of data. At block 320, the normalization module 214 normalizes the second types of data. Normalization may involve, for example, filling in gaps or addressing outliers in the data. The normalization algorithms may be provided by the energy management platform 102 or the user. At block 322, the key/value store 116 stores the normalized second types of data.
The process 300 can be used in various circumstances. For example, the data provided by the external data sources 1041-n, as appropriate, can be received and processed by the energy management platform 102 in accordance with the process 300. Further, suitable portions of the process 300 can apply to data derived from other data processing techniques of the energy management platform 102, such as stream processing and batch parallel processing. Many other uses of the process 300 are possible in addition to the examples discussed herein. For example, other uses of the process 300 may include weather measurements, meter events, energy efficiency measures, grid assets, phasor management unit measurements, and customer information.
At block 408, the stream processor of the stream analytic services module 210 receives the notification to process the data. The notification provided to the stream processor may be based on scheduling logic of the event queue that accounts for load balancing for and availability of computing resources to process the data. The stream processor of the stream analytic services module 210 provides an instruction to the stream processing logic of the stream analytic services module 210 to process the data. At block 410, the stream processing logic of the stream analytic services module 210 processes the data. The stream processing logic may be based on any specifications of the user or an administrator of the energy management platform 102.
The process 400 proceeds to one or more of block 412, block 414, and block 416, which represent examples of different actions that can be taken by the stream processing logic. At block 412, the data engine of the data services module 206 persists the processed data. The processed data may be persisted in the relational database 114 or the key/value store 116. At block 414, the integration services module 204 receives from the stream processing logic an indication of an event, such as an alert, based on the processed data. The alert, in turn, may trigger the integration services module 204 to take action, such as notifying an application or resource, internal or external to the energy management platform 102, about a real-time or near real-time condition relating to energy usage or management. At block 416, the stream processor of the stream analytic services module 210 receives a new stream of data based on the processed data. In response to receipt of the new stream of data, the process 400 may proceed to block 402 to initiate another cycle of the process 400.
The process 400 can be used in various situations. In one example situation, energy loss may be evidence or caused by myriad occurrences, such as energy usage readings on inactive meters (e.g., AMR, AMI), tampered or bypassed meters, and malfunctioning meters. Stream processing in accordance with the process 400 can allow for rapid identification of meters potentially associated with energy loss. With respect to persisting data, a table could be created that stores the identification of the meters associated with energy loss and their related meter data. The table then could be persisted for use by an application of the energy management platform 102. With respect to provision of alerts, once meters associated with energy loss are identified, the process 400 may generate alerts that prompt communications to appropriate field personnel to be dispatched to investigate such meters. In another example situation, a stream of meter data may need to be converted for use as a new stream. With respect to generating a new stream, meter data provided at, for example, 15-minute intervals can be converted to a new stream of aggregated meter data reflecting, for example, one hour intervals. The new stream, in turn, may be processed in accordance with the process 400 and the stream processing logic associated with the new stream. Many other uses of the process 400 are possible in addition to the examples discussed herein. For example, other uses of the process 400 may include: identification and quantification of unbilled energy due to theft and malfunction; identification of opportunities to reduce operational and capital expense by right-sizing system voltage and power factor; estimation of load predication and potential load reduction at multiple aggregation levels; computation of outage metrics by region within the grid distribution system; and examination of dynamic load patterns, voltage abnormalities, and optimal equipment capacities to create a profile of the health of grid assets.
At block 510, the batch processor of the batch parallel processing analytic services module 212 receives the notification to process the batches. The notification provided to the batch processor may be based on scheduling logic of the event queue that accounts for load balancing for and availability of computing resources to process the data. The batch processor of the batch parallel processing analytic services module 212 provides an instruction to the batch processing logic of the batch parallel processing analytic services module 212 to process the batches. At block 512, the batch processing logic of the batch parallel processing analytic services module 212 processes the batches. The batch processing logic may be based on any specifications of the user or an administrator of the energy management platform 102. At block 514, the batch processor of the batch parallel processing analytic services module 212 receives the processed batches. The processed batches may be used in accordance with an application of the energy management platform 102.
The process 500 can be used in various situations. For example, reports relating energy usage can be generated on, for example, a daily, monthly, or yearly basis using batch parallel processing. In this regard, the reports generated by batch parallel processing may aggregate, analyze, and compare data across any number of KPIs, such as periodic (e.g., yearly) energy cost, periodic (e.g., yearly) energy consumption, periodic (e.g., year over year) change in energy cost, periodic (e.g., year over year) change in consumption, energy cost per square area, and energy consumption per square area. Many other uses of the process 500 are possible in addition to the examples discussed herein. For example, other uses of the process 500 may include generation of energy efficiency recommendations across a portfolio of facilities; evaluation of load forecasting statistical models across a portfolio of meters to determine load shedding opportunities; and customer segmentation identification and evaluation.
The machine 600 includes a processor 602 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), or both), a main memory 604, and a nonvolatile memory 606 (e.g., volatile RAM and non-volatile RAM), which communicate with each other via a bus 608. In some embodiments, the machine 600 can be a desktop computer, a laptop computer, personal digital assistant (PDA), or mobile phone, for example. In one embodiment, the machine 600 also includes a video display 610, an alphanumeric input device 612 (e.g., a keyboard), a cursor control device 614 (e.g., a mouse), a drive unit 616, a signal generation device 618 (e.g., a speaker) and a network interface device 620.
In one embodiment, the video display 610 includes a touch sensitive screen for user input. In one embodiment, the touch sensitive screen is used instead of a keyboard and mouse. The disk drive unit 616 includes a machine-readable medium 622 on which is stored one or more sets of instructions 624 (e.g., software) embodying any one or more of the methodologies or functions described herein. The instructions 624 can also reside, completely or at least partially, within the main memory 604 and/or within the processor 602 during execution thereof by the computer system 600. The instructions 624 can further be transmitted or received over a network 640 via the network interface device 620. In some embodiments, the machine-readable medium 622 also includes a database 625.
Volatile RAM may be implemented as dynamic RAM (DRAM), which requires power continually in order to refresh or maintain the data in the memory. Non-volatile memory is typically a magnetic hard drive, a magnetic optical drive, an optical drive (e.g., a DVD RAM), or other type of memory system that maintains data even after power is removed from the system. The non-volatile memory may also be a random access memory. The non-volatile memory can be a local device coupled directly to the rest of the components in the data processing system. A non-volatile memory that is remote from the system, such as a network storage device coupled to any of the computer systems described herein through a network interface such as a modem or Ethernet interface, can also be used.
While the machine-readable medium 622 is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals. The term “storage module” as used herein may be implemented using a machine-readable medium.
In general, the routines executed to implement the embodiments of the invention can be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “programs” or “applications”. For example, one or more programs or applications can be used to execute specific processes described herein. The programs or applications typically comprise one or more instructions set at various times in various memory and storage devices in the machine and that, when read and executed by one or more processors, cause the machine to perform operations to execute elements involving the various aspects of the embodiments described herein.
The executable routines and data may be stored in various places, including, for example, ROM, volatile RAM, non-volatile memory, and/or cache. Portions of these routines and/or data may be stored in any one of these storage devices. Further, the routines and data can be obtained from centralized servers or peer-to-peer networks. Different portions of the routines and data can be obtained from different centralized servers and/or peer-to-peer networks at different times and in different communication sessions, or in a same communication session. The routines and data can be obtained in entirety prior to the execution of the applications. Alternatively, portions of the routines and data can be obtained dynamically, just in time, when needed for execution. Thus, it is not required that the routines and data be on a machine-readable medium in entirety at a particular instance of time.
While embodiments have been described fully in the context of machines, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms, and that the embodiments described herein apply equally regardless of the particular type of machine- or computer-readable media used to actually effect the distribution. Examples of machine-readable media include, but are not limited to, recordable type media such as volatile and non-volatile memory devices, floppy and other removable disks, hard disk drives, optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks, (DVDs), etc.), among others, and transmission type media such as digital and analog communication links.
Alternatively, or in combination, the embodiments described herein can be implemented using special purpose circuitry, with or without software instructions, such as using Application-Specific Integrated Circuit (ASIC) or Field-Programmable Gate Array (FPGA). Embodiments can be implemented using hardwired circuitry without software instructions, or in combination with software instructions. Thus, the techniques are limited neither to any specific combination of hardware circuitry and software, nor to any particular source for the instructions executed by the data processing system.
For purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the description. It will be apparent, however, to one skilled in the art that embodiments of the disclosure can be practiced without these specific details. In some instances, modules, structures, processes, features, and devices are shown in block diagram form in order to avoid obscuring the description. In other instances, functional block diagrams and flow diagrams are shown to represent data and logic flows. The components of block diagrams and flow diagrams (e.g., modules, engines, blocks, structures, devices, features, etc.) may be variously combined, separated, removed, reordered, and replaced in a manner other than as expressly described and depicted herein.
Reference in this specification to “one embodiment”, “an embodiment”, “other embodiments”, “another embodiment”, or the like means that a particular feature, design, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. The appearances of, for example, the phrases “according to an embodiment”, “in one embodiment”, “in an embodiment”, or “in another embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
