POWER CONTROL SYSTEM FOR HOME ENERGY MANAGEMENT

A home energy system includes a distribution assembly with a power bus coupled to interfaces for a utility grid, home loads, distributed energy resources (DERs), and an electric vehicle (EV). Measurement circuitry obtains electrical parameters at the interfaces, and a power control system (PCS) controller monitors an aggregate parameter relative to a capacity constraint of the distribution assembly. When the aggregate exceeds the constraint, the PCS controller commands the DER or EV to reduce active power exchange. If the condition persists for an interval, the PCS controller actuates a relay switch to electrically isolate the DER or EV.
