Examination of improvement effect of self-consumption rate by introducing V2H system

Abstract

In recent years, electric vehicles (EVs) have attracted attention as power storage devices. In this study, the house has residential PV, stationary battery and EV. We examined the self-consumption rate is improved by introducing the V2H in the house. In the house with V2H installed, restriction on SoC of EV battery was set before driving, and storage battery operation was carried out in consideration of the convenience of EV users. Consequently, even if the capacity of the stationary storage battery is halved, the self-consumption rate was improved more than 1.09 times by V2H introduction.
