| Abstract | ||||
| The main objective of this work is to design an optimal – efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Three renewable energy power systems are presented in this paper to select the most optimum one of them. Theses suggested renewable energy systems are stand-alone photovoltaic system, PV- wind-fuel cell hybrid system and PV- wind hybrid system. The sizing, optimization and economic estimation of the proposed systems were performed using HOMER software. HOMER solves the optimization problem to minimize the global cost and provides the optimum wind turbine, PV, battery and fuel cell ratings. In addition, a comparison between the three different suggested power system configurations is illustrated in details. PV- wind hybrid system realized the lowest net present cost and leverized cost of energy. Also, this system was able to provide energy approximately all the day. The battery state of charge varies between 77% to100% and it was found that, the PV- wind hybrid system is more suitable than the others for the selected site and the suggested electrical load. | ||||
