要約(英語): Recently, photovoltaic generation (PV) systems have been integrated into electricity systems in Japan to reduce carbon dioxide emissions and enhance energy security. However, high penetration of PV will cause voltage rise problems especially in suburban distribution systems. One of the promising solutions to address the voltage rise is control of distributed battery energy storage systems by distribution system operators (DSO). When feed-in tariffs for distributed PV end, some customers who own PV will purchase a battery storage system to increase their self-consumption of power. Hence, DSO can reasonably control the voltage by using those batteries if they are located on desirable sites. This paper presents the economic evaluation of batteries as alternative facilities for voltage control such as SVC in each scenario. As a result, the locational capacity value of distributed batteries varied from node to node. The maximum value was 17,800 JPY/kWh/year in SVC 1 scenario, and 8,800 JPY/kWh/year in SVC 0 scenario.
