SYSTEMS AND METHODS FOR POWER VARIABILITY REDUCTION

A control system (100) for providing a control signal (Pr) to an energy storage system (107) to reduce power variability of an energy generation system (101) is provided. The energy storage system is coupled to the power output of the energy generation system and configured to at least one of receive and provide electrical power in response to the control signal. The control system comprises a monitoring unit (112) configured to monitor the power output of the energy generation system and to provide a respective monitoring signal (Psm). The control system further comprises a control signal generation unit (103) configured to generate the control signal from the monitoring signal, wherein the control signal generation unit implements a filtering unit (106) that has a band pass response. The filtering unit passes a predetermined frequency band of the monitoring signal and the control signal generation unit is configured to generate the control signal in said frequency band so as to compensate power variations of the power output of the energy generation system in said frequency band.
