Abstract

Future smart grids are becoming smarter by applying intelligent control techniques. In this paper, a hybrid energy system consisting of wind, photovoltaic and fuel cell designed to supply continuous power to the load. Wind and photovoltaic are the primary power sources of the system to take full advantage of renewable energy around us. The FC is used as a backup and long term storage system. For a stand-alone application, a battery is also used in the system as short term energy storage to supply fast transient and ripple power. In the proposed system, the different energy generating sources are integrated. Dynamic models for the main system components, namely, wind energy conversion system (WECS), PV energy conversion system (PVECS), fuel cell, power electronic interfacing circuits, hydrogen storage tank is developed. Solid Oxide Fuel Cell (SOFC) types of fuel cells has been modeled in this paper & also based on the dynamic component models, a simulation model for the proposed hybrid energy system has been developed using MATLAB Simulink. The overall power management strategy for coordinating the power flows among the different energy sources is presented also in this paper.
