LOCAL METERING RESPONSE TO DATA AGGREGATION IN DISTRIBUTED GRID NODE
First Claim
1. A method for interfacing with a power grid network, comprising:
- receiving multiple inputs at a meter on a consumer side of a point of common coupling (PCC) to the grid network, the inputs indicating an electrical condition of the grid network and local operating conditions at the PCC;
identifying power demand for a local load coupled to the consumer side of the PCC;
calculating a mix of real and reactive power to output from a local energy source, based on the multiple inputs and the power demand for the local load; and
outputting power from the local energy source based on the calculated output power.

Abstract
Data aggregation enables a local control response at a consumer node of a distributed grid network. A consumer node includes a local energy meter. The meter receives multiple inputs indicating an electrical condition of the grid network and local operating conditions. The meter can aggregate the grid network and local operation conditions inputs with power demand for a local load coupled to the consumer side of the point of common coupling monitored by the energy meter. The energy meter calculates a mix of real and reactive power to output from a local energy source, based on the aggregated data. A local power converter outputs the calculated power from the local energy source.
