Optimizing alternative backup power supplies with wind generator to supply isolated loads

The energy output of a wind generator (WG) is variable due to the variation of wind speed at the installation site through the day hours and year months. Therefore, a back-up power supply (BUPS) is necessary for operating WG to supply isolated loads. These BUPS may be diesel generator (DG) and /or alternative sources of renewable energy system (RES) which is available at the installation site. In this work, these BUPSS are optimized and assessed for operating with WG to supply isolated loads. The alternatives of RESs used here are photovoltaic power system (PVPS) and /or battery storage (BS). So, a hybrid model is presented here incorporates the added futures of dynamic modeling and graphic user interface in the power system block set and matlap program to assess the capacity of these BUPSs for operating with WG to supply isolated loads. Also, an economical model has been introduced to optimize the considered BUPSs from economical point of view. These models are applied numerically to estimate the capacity of alternative of WG/ DG, WG/PVPS/BS and WG/ PVPS/DG generation systems to supply an isolated load of a tourist village on the Egyptian coast of Red Sea. Also, these alternatives are optimized economically to supply the studied load.
