要約(英語): Concern for energy security and global warming have led to the integration of solar photovoltaic generation (PV) into electricity systems. The penetration of PV may cause voltage rise problems in distribution systems. This paper proposes voltage control scheme using customer-owned battery considering customer's benefit in distribution systems with high penetration of PV. When feed-in tariffs for PV end, electricity customers who own photovoltaic systems are expected to purchase batteries in order to increase self-consumption. Hence one of the possible solutions to address voltage rise is control of customer-owned batteries. In this paper, we evaluate the impact of voltage constraints on customer's benefit and clarify the technical potential of customer-owned battery for providing voltage regulation. Qualitative analysis has been performed in a distribution system interconnected with large PV locally. Because results show that voltage constraints increase electricity cost insignificantly and reduce opportunity loss to sell PV output, customers who own batteries would allow distribution system operator to use their batteries for voltage regulation.
