BESS and other forms of energy storage can be utilized to diminish rates of curtailment, especially as more solar and wind generation is interconnected to the grid. Load leveling is typically a bi-directional method of operation that requires the BESS power converter to operate both in inverter (DC-AC) and rectifier (AC-DC) modes.
