A frequency control method for isolated photovoltaic-diesel hybrid power system with use of full renewable energy

In this paper, a frequency control method is introduced for photovoltaic-diesel hybrid system by using a load estimator and an energy storage system. The proposed method is compared with a fuzzy based frequency control method. Simulation results show that the proposed method is feasible to reduce the frequency deviations of the isolated power utility and delivers maximum power compared to the fuzzy based method.
