Control system simulation for stand-alone hybrid wind diesel system

Control system developed for hybrid wind diesel system (HWDS) operating as standalone power system is presented. The HWDS consists of a permanent magnet synchronous generator (PMSG) based wind turbine generation system and a diesel generation system (DGS) with synchronous machine. Control system developed for both machine side and load side power converter is simulated. A maximum power point tracking (MPPT) control system is developed and simulated for machine side power converter to track the optimum rotor shaft speed for achieving maximum power extraction through wind turbine. The transition from wind-diesel to wind-only mode of operation is simulated. A dynamic model of HWDS is developed to study the system operating behavior under standalone condition. The complete HWDS is modeled and simulated in MATLAB Simulink environment. Simulation results to validate the performance of developed control system are presented.
