Sizing of a hybrid power system for a house in Libya

This paper presents the design of a hybrid power system for a house in Tripoli-Libya using homer software and BEopt. According to general electrical company in Libya, the house consumes 7845kWh/year, and total area of the house is (1962ft2). The house is simulated using BEopt software. Insulated roof and walls are selected to reduce cooling demand. The hybrid power system proposed consists of a wind turbine, PV panels, and battery storage used when there is no sun and wind energy. That region has an average annual wind speed is above 4 m/s and the radiation of sun is about 7.1 kilowatt hours per square meter per day (kWh/m
²
/day). The proposed PV/wind hybrid power system will be installed on the house. The results show that the optimum configuration meets the house requirements. The lowest levelized cost energy is obtained for a system consisting of 2.8kW PV modules, three 400W wind generator and storage batteries using 56, 200Ah units.
