Abstract: In this paper, a methodology for estimating the optimal design of a stand-alone hybrid wind/photovoltaic (wind/PV) system is developed. The system plan was developed by using the direct algorithm to achieve a minimum cost of energy production (COE) while satisfying the energy demand with a minimum value of loss of power supply probability (LPSP). The collected hourly data for one year 2012 of solar radiation, wind speed and temperature in Basrah city were used in the optimization. Results of the simulation illustrate that the most economic configuration is a stand-alone PV system with LPSP of 1 % and cost of energy production equal to 0.5$/kWh.
