This invention generally relates to smart meters, and in particular, to systems, methods, and apparatus for monitoring and alerting based on energy sources and energy consumption.
A smart grid is an electrical distribution network designed to accommodate suppliers and consumers, and to anticipate and efficiently respond to changing operating conditions. Smart meters can be utilized within a smart grid to enable services such as dynamic pricing, automated control of equipment, usage data, and scheduling and control of loads.
Customers who want to reduce their electrical costs or reliance on the grid can install local alternative power generation capabilities, such as solar panels, wind turbines, and batteries. Such alternative power generation and storage equipment may not be able to meet all of the consumer's power demands all the time, so connection to the electrical grid is usually required. However, coordination among the grid, the alternative power sources, and the load needs to be effectively managed, and a need may exist for modifying power consumption behavior based on available power from local alternative power generation equipment.
Some or all of the above needs may be addressed by certain embodiments of the invention. Certain embodiments of the invention may include systems, methods, and apparatus for monitoring and alerting based on energy sources and energy consumption.
According to an example embodiment of the invention, a method is provided for monitoring a customer's energy consumption from one or more energy sources, and for providing alerts to the customer. The method can include monitoring customer energy consumption from a utility grid; monitoring customer energy consumption from one or more alternative energy sources; determining when the customer energy consumption meets or exceeds a capability of the one or more alternative energy sources; generating an output, based at least on the determination, to indicate actual or forecasted customer energy consumption from the utility grid; and transmitting the output, wherein the output is accessible by the customer.
According to another example embodiment, a system is provided for monitoring and alerting based on energy sources and energy consumption. The system includes a communication interface and a smart meter. The smart meter includes at least one memory for storing data and computer-executable instructions; and at least one processor configured to access the at least one memory and further configured to execute the computer-executable instructions for: monitoring customer energy consumption from a utility grid; monitoring customer energy consumption from one or more alternative energy sources; determining when the customer energy consumption meets or exceeds a capability of the one or more alternative energy sources; generating an output, based at least on the determining, to indicate actual or forecasted customer energy consumption from the utility grid; and providing the output to the customer via the communication interface.
According to another example embodiment, an apparatus is provided for monitoring and alerting based on energy sources and energy consumption. The apparatus includes at least one memory for storing data and computer-executable instructions; and at least one processor configured to access the at least one memory and further configured to execute the computer-executable instructions for: monitoring customer energy consumption from a utility grid; monitoring customer energy consumption from one or more alternative energy sources; determining when the customer energy consumption meets or exceeds a capability of the one or more alternative energy sources; generating an output, based at least on the determining, to indicate actual or forecasted customer energy consumption from the utility grid; and providing the output to the customer via the communication interface.
Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed inventions. Other embodiments and aspects can be understood with reference to the following detailed description, accompanying drawings, and claims.
Reference will now be made to the accompanying figures and flow diagrams, which are not necessarily drawn to scale, and wherein:
Embodiments of the invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
Certain embodiments of the invention may enable detection and coordination of power flow among the electrical grid, local alternative power sources, and loads. For example, the local alternative power sources may include solar panels, wind or other turbine generators, batteries, etc. that may provide some of the power needs of a customer. Example embodiments of the invention may provide messaging information that a customer may utilize in managing their use of certain power resources. For example, during times when the local alternative power sources are not producing enough electrical energy for a certain demand by the customer, power can be routed from the grid to meet the demand. Nevertheless, the customer can control their demand in many scenarios. For example, appliances can be operated during the daytime when solar power is available. Conversely, appliances can be turned off during times when power would need to be drawn from the gird.
According to an example embodiment of the invention, a smart meter may monitor and detect usage from the electrical grid and/or local alternative power sources, and may generate messages than can be made available to the customer. According to example embodiments, the messages may provide information that may be useful for the customer, and may be utilized for modifying usage patterns. In an example embodiment, messages may including an indication of which source is providing the power, pricing information, etc. According to and example embodiment, the messages may be provided to the customer through a wide variety of communication channels. For example, SMS messaging, e-mail, automated voice messaging, webpage, etc. According to other example embodiments, certain appliances or loads within the customer's premises may be controlled based on the messaging, and/or other pre-arranged agreements or schedules.
According to certain example embodiments, when the customer's own electricity generating source is generating and distributing all of the power to the customer, the smart meter may not read or register usage from the grid for billing by the utility. In an example embodiment, when the customer's own electricity generating source is not producing enough power to meet the demand required by the customer, the additional needed electricity may start flowing from utility via the grid, and the smart meter may monitor and read or register the grid power usage for billing. In another example embodiment, when the customer's own electricity generating source is not producing enough power to meet the demand, coordination to supply the additional needed electricity may include (a) drawing all needed power from the grid, or (b) blending and coordinating power from the grid and available power that is being locally generated. According to an example embodiment, the smart meter may be configured sell the excess energy to the utility when the customer's own generation source is generating energy that exceeds the demand of the customer. According to an example embodiment, when the excess energy is providing power to the grid, the smart meter may read or register the direction and amount of power flow.
According to example embodiments, messages may be generated and sent to the customer whenever there is a status change, for example, in power flow from or to the grid. According to example embodiments, the messaging may help the customer to be aware of their energy usage and cost, and may provide information for taking necessary actions to reduce usage, or to knowingly use the grid power at a communicated, predetermined, or scheduled price. According to an example embodiment, the messaging may alert the customer when they are making money from their generation capacity and usage. According to example embodiments, the messages may be generated and sent according to certain pre-determined thresholds.
Various hardware components and computer readable modules for monitoring and alerting based on energy sources and energy consumption or production, according to example embodiments of the invention, will now be described with reference to the accompanying figures.
According to an example embodiment, the smart meter 102 may deliver messages to the customer 122 via wired communications 126, through one or more networks 128, or via wireless communication 126 (such as SMS, cell, etc.).
