Parallel operation of wind turbine, fuel cell, and diesel generation sources

We investigated a small isolated hybrid power system that used a parallel combination of dispatchable and nondispatchable power generation sources. The nondispatchable generation came from a nature-dependent wind turbine, and the dispatchable generations were a fuel cell and a diesel generator. On the load side, the nondispatchable portion was the village load, and the dispatchable portion was the energy storage, which could be in many different forms (e.g., space/water heater, electrolysis, battery charger, etc.) The interaction among different generation sources and the loads was investigated. Simulation results showed the effect of the proposed system on voltage and frequency fluctuations.
