Abstract

The present disclosure provides curtailing photovoltaic (PV) power output and autonomous load breaking in a backup mode of an electrical system. The electrical system includes a PV system, an energy storage system having a storage converter, and an energy control system. The energy control system is electrically coupled to the PV system, the energy storage system, and a plurality of backup loads. The electrical system includes an autonomous load breaker electrically coupled to a first backup load. When the energy control system switches from an on-grid mode to the backup mode, the storage converter adjusts the frequency of the power supplied to the backup side of the energy control system to a setpoint frequency that curtails PV power output, and the autonomous load breaker electrically disconnects the first backup load from the energy control system.
