Abstract: A power output control and compensation (PCC) circuit operates within a distributed energy resource (DER) system. The PCC circuit is located in a battery power conversion system (PCS) and includes an input terminal to connect with a power source and an output terminal to connect with an electrical panel or load. A current sensing device is coupled between the input and the output terminals to measure a power level of the power source. A relay is coupled between the current sensing device and the output terminal and a processor selectively connects power from the power source to the electrical panel or the load based on the measured power level or based on other power measurements within the DER system.

Abstract: Unintentional islanding (UI) of a circuit of distributed energy resources (DERs) may leave area electrical power systems (EPS), external to the DER circuit, energized. Thus, UI detection methods have been developed to detect unintentional islanding and trigger a UI response. However, individual UI detection methods have various deficiencies. Thus, a consensus-based UI detection process is disclosed that builds a consensus from multiple UI detection sources, optionally implementing different UI detection methods. The redundancy in this consensus-based UI detection process provides robust, sensitive, selective, and cybersecure UI detection for the entire DER circuit. For example, the consensus-based UI detection process may eliminate or reduce non-detection zones, avoid false positives, thwart cyber-attacks, and/or the like.
