Multi-functional energy storage system for supporting solar PV

However, as the solar generation decreases and the BESS begins operating as a load, the feeder load power increases as a result and eventually reaches the high level setpoint of 5250 kW at t = 4.2 s. Once this setpoint is reached, the BESS begins increasing its output and transitions to the inverter mode of operation (discharging) at t = 5 s.
