Design and economic analysis of fotovoltaic (PV), wind and hybrid systems

In this study, the production of electrical energy from fotovoltaic system (PVS), wind energy system (WES) and hybrid system?s (HS) was investigated, and the design, comparison and economic analysis of the systems were performed. In order to carry system designs out and determine the technical and economical parameters of each system, PVsyst and HOMER programs were used. Belen, Gelibolu, Konya, Sinop, Kırklareli and Karaman cities were selected as the design areas. The system costs and levelized costs of energy were investigated for three different load of 1500 kWh, 2500 kWh and 3500 kWh cases annually and the effect of capacity shortage fraction on the systems was examined. The systems were designed as grid connected and stand alone systems. It was determined that the HS is more cost-effective than the PVS and WES for stand alone system designs. The cost of energy is high for stand alone systems in today?s conditions. Grid-connected systems were examined for cases without/with feed-in tariff. The results of PVsyst and HOMER for grid-connected PV systems without feed-in tariff were only compared for an annual load of 1500 kWh and it was seen that the results of optimum system obtained from both programs were close to each other. The levelized costs of energy vary between 0.267 $/kWh and 0.367 $/kWh for PVS, between 0.072 $/kWh and 0.36 $/kWh for WES, between 0.074 $/kWh and 0.393 $/kWh for HS in the case of feed-in tariff. According to the obtained results, it is determined that the grid connected systems are more cost-effective than stand alone systems.Key Words: Photovoltaic Module, Wind Turbine, PV System, Wind Energy System, Hybrid system, PVsyst, HOMER
