This paper presents control strategy of hybrid fuel cell distributed generation system (HDGS) during voltage sag in distribution systems. The proposed control strategy is based on fuzzy logic and allows the hybrid distributed generation system to operate properly during the voltage sags in distribution systems. For tuning the parameters of fuzzy logic controller, the PSO (particle swarm optimization) algorithm has been used. Simulation results are given to show the overall system performance including power control and voltage sag ride-through capability of the proposed control strategy.
