DATA AGGREGATION WITH FORWARD PREDICTION FOR A DISTRIBUTED GRID NODE
First Claim
1. A method for interfacing with a power grid network, comprising:
- receiving grid condition information at a meter on a consumer side of a point of common coupling (PCC) to the grid network, wherein the grid condition information includes an aggregation of multiple inputs indicating an electrical condition of the grid network and local operating conditions at the PCC, including local power demand;
accessing operating history for a local control node, the operating history including records of previous power output for various grid conditions and operating conditions at the PCC;
calculating an output power to generate with a local power converter coupled to the consumer side of the PCC, based on the multiple inputs, the local power demand, and the operating history; and
outputting power from the local power converter based on the calculated output power.

Abstract
Data aggregation enables a local control response based on forward prediction at a consumer node of a distributed grid network. A consumer node includes a local energy meter that receives grid condition information, including an aggregation of multiple inputs indicating an electrical condition of the grid network, local operating conditions at the PCC, and local power demand. The consumer node accesses operating history for a local control node, the operating history including records of previous power output for various grid conditions and operating conditions. Based on the operating history and the aggregation information, the consumer node calculates an output power to generate with a local power converter, which outputs the power based in accordance with the calculation.
