Suppression of PV output fluctuation using EV in a electric power system

摘要

In recent years, electric vehicles (EV) are attracting attention not only from the viewpoint of transportation but also from utility as a household power storage device. For these reasons, the authors have considered using EV as an electric storage device in a small scale system including photovoltaic power generation. However, due to limitation of the control speed of EV, the sufficient control characteristics could not be obtained. Therefore, in this study, we attempted to improve the control characteristics by introducing a super capacitor in the proposed system.
