A method that PV-battery power generation system support the frequency of the grid was provided. The main design method was using fuzzy control to classify the real-time frequency of grid. Taking account of the grid current condition, the actual PV power output under different weather cases and the status of battery, specific operation mode was established. The functionality of providing or absorbing active power from grid was achieved by the cooperation between PV and battery. The feasibility of this simulation design was verified by the system testing. The results show that this design can realize the status transform between the different operation modes and the design has a great capability for supporting grid frequency.
