Abstract: 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 an energy storage based conventional control method and 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 both of the methods.

Keywords: frequency control; hybrid power systems; load estimator; energy storage systems; ESS; photovoltaic-diesel power; hybrid power systems; fuzzy control; simulation; frequency deviations; isolated power utility.
