An optimization approach of hybrid PV-wind renewable energy systems for power generation in Egypt

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/m(2)/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/m(2) (at Cairo), maximum value of 2065 W/m(2) (at Hurghada), a mean value of 1250 W/m(2), and a standard deviation value of 348 W/m(2).
