Power Quality Enhancement to Sensitive Loads with PV Based Microgrid System

Now a days not only emphasis is given on reliability of energy sources but also on cleanliness on energy sources. Microgrid based distribution energy resources are used for sensitive loads to improve the reliability of system. In current scenario of competitive energy market, photo voltaic (PV) based renewable energy resources are getting attention for low maintenance, pollution free and low running cost. So, PV based microgrid system is optimal solution for different distribution energy resources. Hysteresis current control & SPWM voltage controller is used in the proposed system for different modes of operation. The performance of this model has been studied in grid connected mode and under islanded mode. The effectiveness of proposed control strategies is studied in simulation for different grid connected modes and different loading conditions.
