This paper presents frequency fluctuation analysis of an isolated hybrid power system. Hybrid system includes Wind, Diesel-Engine Generator (DEG) and Fuel Cell (FC) system. This hybrid system is connected to the local utility point and it may connect to the local electric grid. The impact of the FC system on the frequency stability of an isolated hybrid system has been analyzed. Due to limited storage capacity, the limits of hydrogen volume have also been incorporated. Simulation results show that the FC system can give better performance for stabilizing the frequency of the system in comparison to conventional distributed sources like DEG, FC system contribution is extremely useful in both cases when the load rises and also when the load drops.
