No. 12/208,422, the entire contents of which are herein incorporated by reference. The present application is also related in some aspects to commonly owned and co-pending application entitled “Policy-Based Energy Management”, which was filed on Sep. 11, 2008, and was assigned U.S. patent application Ser. No. 12/208,510, the entire contents of which re herein incorporated by reference.
This invention discloses an approach for managing dependencies among objects (e.g., devices) of a system. Specifically, the present invention provides a solution for energy management using linkages among objects.
As energy prices continue to rise, companies and individuals are seeking ways to reduce consumption and manage shortage situations. Currently, methods for managing energy shortage situations are limited, as managing energy usage of objects in an infrastructure is a nascent industry. A few early solutions include: WebSphere XD, which allows application servers to be tuned down to lower energy consumption modes (WebSphere is a trademark of IBM Corp. in the United States and/or other countries); and objects may be connected to home appliances (e.g. air conditioner) that allow the energy company to turn off energy to the appliance when a shortage occurs. This only enables an on/off situation for selected objects. Currently, energy is provided to all objects in an equal manner. In a true utility fashion when an object is connected to the energy grid at a residence or place of business energy is indiscriminately supplied to that object. There is no preference given to one object over another.
In view of the foregoing, there exists a need for an approach that solves at least one of the deficiencies in the related art.
For optimal efficiency in an energy management system, it is beneficial to control the energy throttling among all objects in an intelligent manner. For enterprise and consumer environments, many objects can be linked and are dependent on each other. As such, adjustment of one piece of a system can have downstream effects on other items. For example, a swimming pool can have multiple dependent objects such as a filter, a chemical dispenser, a heater, etc. Being able to identify these linkages and effects of changes across the system will be critical for the energy manager. Under the present solution, dependencies and relationships are stored and are updatable by consumers and optionally manufacturers through a local user interface (UI) or web interface. These dependencies and relationships are stored in a “collection profile” which describes the capabilities of objects. When a request to reduce energy is received the system can query the collection profile to determine the downstream effect of reducing energy to a single object. The collection profile will identify which other objects rely on that object and would also need to have energy reduced.
A first aspect of the present invention provides a method for managing linkages among objects of a system, comprising: identifying a set of objects in the system; creating linkages among the set of objects based on known dependencies and relationships between the objects; receiving an energy conservation request; and managing energy to the set of objects based on associated energy policies and the linkages.
A second aspect of the present invention provides a system for managing linkages among objects of a system, comprising: a module for identifying a set of objects in the system; a module for creating linkages among the set of objects based on known dependencies and relationships between the objects; a module for receiving an energy conservation request; and a module for managing energy to the set of objects based on associated energy policies and the linkages.
A third aspect of the present invention provides a computer readable medium containing a program product for managing linkages among objects of a system, the computer readable medium comprising program code for causing a computer system to: identify a set of objects in the system; create linkages among the set of objects based on known dependencies and relationships between the objects; receive an energy conservation request; and manage energy to the set of objects based on associated energy policies and the linkages.
A fourth aspect of the present invention provides a method for deploying a system for managing linkages among objects of a system, comprising: deploying a computer infrastructure being operable to: identify a set of objects in the system; create linkages among the set of objects based on known dependencies and relationships between the objects; receive an energy conservation request; and manage energy to the set of objects based on associated energy policies and the linkages.
A fifth aspect of the present invention provides a computer-implemented method for managing linkages among objects of a system, comprising: identifying a set of objects in the system; creating linkages among the set of objects based on known dependencies and relationships between the objects; receiving an energy conservation request; and managing energy to the set of objects based on associated energy policies and the linkages.
A sixth aspect of the present invention provides a data processing system for managing linkages among objects of a system, comprising: a memory medium comprising instructions; a bus coupled to the memory medium; and a processor coupled to the bus that when executing the instructions causes the data processing system to: identify a set of objects in the system, create linkages among the set of objects based on known dependencies and relationships between the objects, receive an energy conservation request, and manage energy to the set of objects based on associated energy policies and the linkages.

I. General Description
As indicated above, for optimal efficiency in an energy management system, it is beneficial to control the energy throttling among all objects in an intelligent manner. For enterprise and consumer environments many objects can be linked and are dependent on each other. As such, adjustment of one piece of a system can have downstream effects on other items. For example, a swimming pool can have multiple dependent objects such as a filter, a chemical dispenser, a heater, etc. Being able to identify these linkages and effects of changes across the system will be critical for the energy manager. Under the present solution, dependencies and relationships are stored and are updatable by consumers and optionally manufacturers through a local UI or web interface. These dependencies and relationships are stored in a “collection profile” which describes the capabilities of objects. When a request to reduce energy is received the system can query the collection profile to determine the downstream effect of reducing energy to a single object. The collection profile will identify which other objects rely on that object and would also need to have energy reduced. Being able to identify these linkages and effects of changes across the system will be critical for good energy management.

Under the present invention, each object, entity, etc. is identified and enrolled into the system. This may occur manually, through auto-discovery by PCM 50 or by device 54A-N self-enrolling to PCM 50. Once enrolled, PCM 50 maintains a database of objects and their attributes. Sample object attributes are as follows:
Object ID=0487
Object name=“refrigerator01”
Average energy consumed=50
Throttle capabilities=“on/off”
Quiesce first=“no”
Regardless, this functionality may be implemented with a single energy management server, groups of servers, or a hierarchy of servers. A hierarchy is the preferred embodiment for an enterprise system, as that allows for delegation.
Once the objects have been identified, a consumer or system administrator will creates linkages among the objects, based on known dependencies and relationships between the objects. In general, the identification and/or linking of devices can be accomplished by accessing or querying a set of collection profiles. In general, collection profiles describe the capabilities of objects including, but not limited to:
These collection profiles could be stored centrally in a database that is attached to the management system or they could be embedded locally in each object. If embedded locally the collection profile would require persistent memory or storage in each object. Many objects in the home already have this type of persistent storage (thermostats, computers, home automation systems controlling lights and other objects, etc.). Those objects that don't have this capability would require new function from the manufacturer or an in-line object between the energy cable and the outlet known in the art.
In addition to storing the collection profile, a communications protocol with an accompanying API is employed to query the object's collection profile.
To detect object dependencies, the system would query the collection profiles stored either locally in a database or query the network for all existing objects using the APIs described earlier. Detection could then be automatic in determining what objects are present. In this system every object would have a universal unique identifier (UNID) and typically a manufacturer's part number. If a new object was detected the system would query external systems on the internet for default collection profile information. After that step (or in the event it is unknown) the user is then given the option to customize or accept the default collection profile. Since many consumers have unique situations and dependencies among objects this gives them an opportunity to optimize the collection profile.

Regardless, once all the objects are identified and dependencies and relationships are established the system will then be able to display those dependencies upon query and take actions based on energy reduction requests. From the perspective of the overall system or an outside request to reduce energy there exists logical or physical groupings of objects rather than individual objects themselves. In addition, each of these collections will have an Energy Policy such as policies 58 of
The following section will discuss various illustrative scenarios:
Consumer Home Scenario:
One example is a consumer swimming pool that has water heaters, chemical dispensers, water filters, lights, patio heater and water pumps. A consumer may consider the swimming pool to be a noncritical system in the event of an energy shortage. These systems all work together and if energy is shut off from the water filter it may make little sense to supply energy to the heating and pump systems. The pump and heating systems may have dependences on the current temperature or thermometers, while the chemical and cleaning systems may have dependencies on the pumps, the heating system may have a relationship to the electric pool cover position and so forth. The system may shut off underwater lights and heater together. If more energy still needs to be throttled, then shut off the pump as a secondary dependency.
Enterprise IT Scenario
Another example involves an enterprise environment that could be managed at the software level (load balancer/Enterprise Workload Manager (EWLM) linked to web server cluster linked to DB2 database) or hardware level (air conditioners linked to a section of the data center linked to specific servers, linked to lights, etc). Powering-off enough servers in a defined section may lead to turning off the air conditioner for that section, along with the lights, etc.
