Modeling of a wind diesel integrated system (WDIS) is done to perform under varied wind and load conditions on MATLAB Simulink platform. This hybrid system is design in such a way that uunder low wind conditions, a diesel generator feeds the required power to the load. A load flow controller is designed for WDIS to control the load flow depending on the load condition. The power controller redu...
