Control system for hybrid wind diesel based microgrid

Control system developed for hybrid wind diesel system (HWDS) based microgrid is presented. The hybrid system consists of six double fed induction generator (DFIG) based wind turbine generation system, a diesel generation system with synchronous machine and electrical power grid supply. Control system developed for both rotor side and grid side power converter is simulated. A maximum power point tracking (MPPT) control system is developed and simulated for rotor side power converter to track the optimum speed for achieving maximum power extraction from available wind. Vector control based voltage regulation system is developed and simulated for grid side power converter. A dynamic model of HWDS is developed to study the system operating behavior under isolated wind diesel mode and grid connected mode. The complete HWDS is modeled and simulated in MATLAB Simulink environment. Simulation results to validate the performance of developed control system are presented.
