Abstract

A surge of needs for the low carbon society promotes a spread of electric vehicle (EV). EVs could be charged at night simultaneously. That could cause severe voltage drop. Typical charger for EV employs the self-commutated inverter, which can control both active and reactive powers in principle. The authors have investigated potential availability of EVs for the distribution system operation qualitatively, and have concluded that the utilization of reactive power from EV charger could provide great potential for voltage regulation in the distribution system without loss of EV owner's convenience. The authors have proposed some voltage regulation algorithms using EVs. This paper proposes a new algorithm - a centralized control method in which the distribution system operator collects information of each EV in the distribution system and controls them.
