A battery energy storage controller (BESC) can balance the mismatch of power demand and supply and improve flexibility and resiliency of seaport microgrids. However, it is required to test functionality of the BESC, and validate that it can balance the power supply–demand imbalance by charging and discharging the battery.

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
