Abstract

Different criteria of selecting the right sizing of different components of hybrid renewable energy power plant at the most preferable economical and logistical environmental considerations are discussed. A methodology to perform the optimal sizing of an autonomous hybrid PV-wind system is discussed considering the fact that the potential of the wind and solar energy is not equal in Egypt. Optimization study of a hybrid PV/wind system is based on the availability of sunshine all over the year with global solar radiation varying from 5 to 8 kWh/m²/day and with wind speed varying from 5 to 13 m/s is needed which is available in Egypt in different locations. The storage unit containing an energy B(t) of hybrid solar-wind energy at different locations in Egypt has a minimum value of 870 W/m² (at Cairo), maximum value of 2065 W/m² (at Hurghada), a mean value of 1250 W/m², and a standard deviation value of 348 W/m².
