Abstract

This paper evaluates the performance of a fuzzy based power flow control of grid connected hybrid system. The hybrid system composed of a Photo Voltaic (PV) array and a Proton Exchange Membrane Fuel Cell (PEMFC) is considered. The Photo Voltaic (PV) array normally uses a Maximum Power Point Tracking (MPPT) technique to continuously deliver the highest power to the load when there are variations in irradiation and temperature which make it become an uncontrollable source. In coordination with PEMFC, the hybrid system output power becomes controllable. Two operation modes, the Unit -Power Control (UPC) mode and the Feeder-Flow Control (FFC) mode, can be applied to the hybrid system. In the UPC mode, variations in load demand are compensated by the main grid because the hybrid source output is regulated to reference power by using an adaptive fuzzy controller. The proposed operating strategy with a flexible operation mode change always operates the PV array at maximum output power and the PEMFC in its high efficiency performance band, thus improving the performance of system operation, enhancing system stability, and decreasing the number of operating mode changes. This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies.
