Enel has been granted a patent for apparatuses, systems, and methods of apportioning an aggregate maneuver. The patent describes an aggregation engine that coordinates an aggregate response to a request to change power of one or more sites. The engine determines participation opportunity information for site changes in power and transmits it to site controllers. It receives commitment information from the controllers and adjusts the participation opportunity information until the aggregate change in power is within a threshold level of the target change in power.

Aggregation engine for coordinating power changes in multiple sites
A recently granted patent (Publication Number: US11764580B2) describes an aggregation engine that coordinates an aggregate response to a request to change power of one or more sites. The aggregation engine includes a memory to store parameters describing the request and one or more processors to determine participation opportunity information and transmit it to site controllers. The site controllers control distributed energy resources (DERs) at the sites and optimize the operation of the electrical system based on the participation opportunity information. The site controllers provide commitment information indicating the level of the site change in power contributing to bringing the aggregate change in power toward the target change in power. The aggregation engine determines the aggregate change in power, calculates a combined site benefit, and compares it to a threshold. If the combined site benefit is below the threshold, the participation opportunity information is modified based on the commitment information. The modified participation opportunity information is then transmitted to the site controllers.
The aggregation engine can modify the participation opportunity information by changing the associated benefit for the site change in power. It can modify the participation opportunity information to optimize attaining the target change in power by seeking to increase the aggregate change in power and reduce the aggregate benefit to the sites. The participation opportunity information can also indicate how the associated benefit for the site change in power varies over a future period of time based on expected fluctuations in demand for electrical power.
The patent also describes a computer-implemented method that follows a similar process as the aggregation engine. The method involves receiving parameters describing the request, determining participation opportunity information, transmitting it to site controllers, receiving commitment information, determining the aggregate change in power, calculating a combined site benefit, comparing it to a threshold, and modifying the participation opportunity information if the combined site benefit is below the threshold.
Additionally, the patent describes an electrical system controller that communicates with DERs and the aggregation engine. The controller receives participation opportunity information, transmits commitment information, determines an extended control plan based on the modified participation opportunity information, controls the DERs according to the extended control plan, and communicates site commitment information to the aggregation engine.
Overall, the patent presents an aggregation engine and related methods and systems that enable coordinated responses to requests for power changes in an electrical system, optimizing the operation of distributed energy resources at multiple sites.
