Abstract: This paper proposes a method to operate a grid connected hybrid system which comprises photo voltaic (PV) array and proton exchange membrane fuel cell (PEMFC). To deliver highest power to load continuously PV array uses maximum power point tracking (MPPT) technique when there are variations in irradiation and temperature, and makes it as an uncontrollable source. The output power of hybrid system becomes controllable with the coordination of PEMFC. The coordination of the two operating modes unit-power control (UPC) mode and the feeder-flow control (FFC) mode are applied to the hybrid system and determination of reference parameters are presented. The proposed operating strategy operates the PV array at maximum output power and the PEMFC with high efficiency performance band to enhance the performance of the system operation, system stability and decreasing the number of operating mode changes.
