New hybrid system of fuel cell power plant and wind turbine for household consumption

This paper has been suggested a hybrid system of fuel cell power plant and wind turbine. The proposed system connected to grid for home power consumption. The operational cost of the system in wind energy has different effects. In fuel cell power plant (FCP), Genetic algorithm is used to find optimum output power. FCP can produce both electrical energy and thermal energy at the same time, Therefore it tried to supply thermal load and electrical load. Combination of wind turbine and FCP with local grid results in lower operational cost than that of individual units. For analyze the operational cost a Cost function consist of cost of energy, electrical power from wind energy, power trade with the local grid, thermal recovery from the FCP, Setup Fee of FCP and maintenance cost are used. The tariff for electricity is variable and loads have changed in every time. A wind energy unit is used to commute in Mashhad, Iran. The operation of the fuel cell power plant system is planned to optimize cost according to thermal load and electrical load demand, available wind power and different tariffs for buy and selling electricity of local grid. The obtained results confirm the capability of the proposed system.
