The development of advanced energy management systems for efficient and environment friendly society require proper design. Modeling and simulations are performed on the design models for their validity in real time applications. The book presents the modeling of the hybrid wind and fuel cell energy systems using MATLAB SIMULINK toolbox. The wind turbine coupled to doubly fed induction generators combined with the Solid Oxide Fuel Cell to meet the load demand. The fluctuations in the output of the Wind Turbine due to wind speed variations are taken care of by the Solid Oxide Fuel Cell. CUK converter is used to increase the voltage from the non-conventional energy sources. The inverter converts DC voltage to the variable AC voltage given to the load. The main advantage of the hybrid system is to provide Continuous power supply to the load.
