Power Management in a Hybrid Grid Involving Photo Voltaic and Proton Exchange Membrane Fuel Cell

Abstract

The ever growing energy demand explored the generation of power by distributed resources. The distributed resources like photovoltaic, wind, fuel cell etc. are available in nature at free of cost. Photovoltaic cell is used to produce electrical energy by tracking energy from solar irradiation. Perturbation and Observing method is one of the option to track the concentrated power from solar irradiation. It is a clean source, but intermittent in nature. This is overcome by integrating a fuel cell (FC), the new energy source. Proton Exchanging Membrane (PEM) fuel cell is integrated with PV, and this hybrid DC source is integrated to micro grid using power electronic interfacing devices. The design of proper controller operation makes it to work in grid connected mode. The simulation is performed using Matlab-Simulink environment and results validates the performance of hybrid system.
