A case study of PV-wind-diesel-battery hybrid system

Abstract

In this paper, a mountain house in Sakarya, Turkey, which are mainly powered by renewable energy resources rather than the conventional ones, are designed. Therefore, numerous hybrid renewable power generating systems including the components like wind turbine, PV, diesel generator and battery are considered in different configurations. Eventually, they are technically and economically analyzed by using the well-known HOMER software. Furthermore, a sensitivity analysis is also performed considering variations in two important parameters, namely wind speed and solar irradiation. According to the results, the hybrid power generation with the optimal hybrid configuration system includes a 2 kW photo voltaic array, a 1 kW wind turbine, a 1 kW diesel generator, a 1 kW power converter and 12 batteries. In addition, this system has the net present cost of 29,304 $ as well as the cost of energy as 0.752 $/kWh. Lastly, the optimum hybrid system is then compared to the other hybrid systems regarding some non-eco-friendly pollutants.
