Application US20190356164

a Distributed Energy Resource (“DER”) controller of distributed DER controllers, the DER controller coupled to manage a power-exchanging DER associated with a power grid, wherein the DER controller manages the DER to satisfy a DER quality of service constraint or constraints,

wherein the DER controller is communicatively coupled to a secure, distributed transaction ledger that receives data sent by the DER controller and received from one or more other distributed DER controllers of the distributed DER controllers, the data comprising initial data that comprises a power range,

wherein the DER controller is configured to receive an initial ratio value from the secure, distributed transaction ledger,

wherein the initial ratio value is based on the power range and other power range data from the one or more other distributed DER controllers of the distributed DER controllers,

wherein the DER controller is further configured to use the initial ratio value to set a local control action level to an initial level, and use DER-specific information of the power-exchanging DER to determine condensed information comprising one or more scalar or vector values that represent the DER-specific information in a more compact form than the DER-specific information, and to communicate the condensed information to the secure, distributed transaction ledger, wherein the local control action level is local to the DER controller,

wherein the DER controller is further configured to perform iterations based on communication with the secure, distributed transaction ledger to update local optimization variables, including variables defining control actions, until the secure, distributed transaction ledger determines that the iterations have satisfied a defined condition, and

wherein the iterations are performed to: receive a step size value and a global value from the secure, distributed transaction ledger, wherein the step size value and the global value are calculated based on the condensed information and other condensed information from the one or more other distributed DER controllers of the distributed DER controllers, determine a step direction, control the power-exchanging DER with an adjustment based on the step size value and the step direction to approach optimal control values satisfying the specified aggregated load power consumption level, re-determine updated condensed information that updates the condensed information and comprises one or more updated scalar or vector values that represent the DER-specific information after the adjustment, and communicate the updated condensed information to the secure, distributed transaction ledger.

receiving, by a system comprising processors associated with plurality of ledgers together forming a secure, distributed transaction ledger, respective condensed datasets representative of respective Distributed Energy Resource (“DRE”)-specific information received from respective load controllers, wherein the respective DRE controllers are coupled to control a power-exchanging DER associated with a power grid, and wherein the respective condensed datasets are smaller in size than respective full datasets associated with the respective DER controllers;

determining a global value and a step size based on the respective condensed datasets and a specified aggregated control action level;

sending the global value and the step size to the respective DER controllers for use in adjusting respective local power consumptions of the respective DER controllers to satisfy the specified aggregated control action level;

receiving respective updated condensed datasets from the respective DER controllers that update the respective condensed datasets, wherein the respective updated condensed datasets are based on the respective DER-specific information associated with the power-exchanging DER of the respective DER controllers after the adjusting of the respective local power consumptions in respective step directions determined by the respective DER controllers; and

determining, from the respective updated condensed datasets, whether the respective DER controllers have satisfied the specified aggregated control action level to a defined extent, and in response to determining that the specified aggregated control action level has not been satisfied to the defined extent: determining an updated global value and an updated step size based on the respective updated condensed datasets and the specified aggregated control action level, and sending the updated global value and the updated step size to the respective DER controllers for use in further adjusting the respective local power consumptions to satisfy the specified aggregated control action level.
