A voltage control method using EVs in the power distribution system including a mass of PVs

Abstract

This paper proposes a method to control the distribution line voltage utilizing EVs which are connected to the power distribution system. The proposed method adjusts the amount of charge or discharge power of EVs cooperative with PCSs. As a result, the distribution line voltage was maintained within the specified voltage range and the PV opportunity loss was reduced 30.3 points compared with the P control of PCSs. This paper clarifies that EVs are useful as the equipment for maintaining the voltage in the power distribution system.
