POWER QUALITY OF A SMART GRID USING MPPT AND PWM TECHNIQUE

In this paper A Renewable Energy system, Hybrid type using wind and Solar Energy system is proposed. Here two back to back converters using IGBT are interfaced with Permanent Magnet Synchronous Generator (PMSG) and Photo Voltaic Systems (PV) connected to linear load. A capacitor is connected between the Back to Back converters to maintain a steady voltage and to reduce the ripples. A Battery Energy storage system (BESS) is connected between the back to back converters. Battery Energy storage system gets charged when wind and PV energy is sufficient to the load and it Supplies when required by the load. Maximum Power point Tracking (MPPT) technique is implemented as a control mechanism for wind and PV systems to maintain unity power factor at the PMSG by controlling the generator side converter .and to improve the power quality. MATLAB/SIMULINK software is used to simulate the results to verify the impact of control strategies on the system for variable wind speeds and variable irradiance.
