Abstract

With consideration of the increasing energy demand and deficit of fossil fuel resources, the best way for the conquest of renewable resources alternation is the use of hybrid system. In this research, the performance of wind-photovoltaic hybrid system for providing the required electrical energy for a big ministerial building in Kermanshah city is investigated. The required electrical load for the month of a year was calculated 178000 kWh/year by using average electrical energy consumption. With consideration of wind average velocity for hours of a year, Weibull and Rayleigh distribution functions for this location was determined. Also, the power and annual energy of each turbine using wind speed data was calculated. The amount of average solar radiation by use of solar energy relations was calculated, and then, with consideration of annual total energy, the required annual wind energy versus solar cell surfaces selection was determined. Finally, the type and number of turbines by using of their technical specification for each surface selection of solar cells was determined and the performance of hybrid system including 300 m2 photovoltaic solar cells and a 20 kW turbine for providing electrical energy for this building was investigated and compared.
