Influence of EV on grid power quality and optimizing the charging schedule to mitigate voltage imbalance and reduce power loss

The penetration of Electric Vehicle (EV) on the Indian grid and its positive impact can be seen if the EV's are co-ordinated. The co-ordinate charging and discharging of EV's can improve the voltage profile and reduce the power transmission loss. Primary distribution of Guwahati City is simulated using actual data. Voltage profile and transmission loss have been analyzed considering various levels of EV penetration and charging patterns. It is shown that coordinated charging and discharging of EV's on the grid will flatten the voltage profile of a bus as well as reduce the power loss.
