Droop control method of energy scheduling mechanism for grid tied solar PV system of electric vehicle

Maintaining constant voltage and constant frequency between distributed generation is the foremost need nowadays from different magnitude of two dynamic energy generation. Droop control method having minimum THD is used with the help of proper tuning of PI controller for achieving the constant voltage and frequency from different magnitude of generation. Through this approach, the prediction and control become easy for the economic load dispatch center for dispersed generation in case of normal, faulty and emergency situations. The bidirectional energy supply between solar PV and EV depend on solar insolation temperature and SOC of the EV battery decide the difference of voltages which ultimately decide the direction of power flow. Harmonic reduction done by suitable SPWM firing pulse given to switches of the inverters. Passive filter is used to reduce theharmonics. EV operating as source and load gives the with droop controller giving minimum THD and bidirectional supply of EV charging station and power grid gives novel configuration of the work.
