Validation of voltage regulation method in distribution system utilizing electric vehicles

A surge of needs for the low carbon society promotes a spread of electric vehicle (EV). EVs could be charged at night simultaneously, as a result, severe voltage drop may happen. Typical charger for EV employs the self-commutated inverter, which can control both active and reactive powers in principle. The authors are investigating the availability of EVs for the distribution system operation qualitatively, and have proposed voltage regulation algorithms using EVs. This paper validates the performance of proposed algorithms from the practical points of view based on the Monte Carlo simulation.
