Wind-photovoltaic systems for isolated load condition

Hybrid systems are attracting widely due to its operating features which can operate in all aspects of climatic changes. In this work, a self excited induction generator (SEIG) combined with PV array is used for the hybrid system. A variable wind speed is incorporated in this work. The simulation is done using MATLAB/Simulink. The control scheme verified using Active power control Technique (APC) and Direct power control (DPC) technique. It provides full control of active and reactive power. An LC filter is used to reduce the higher order harmonics. A detailed MATLAB simulation is done and results are presented to show effectiveness of controllers in hybrid systems for isolated conditions.
