在电力领域，日本政府制定了到2030年光伏引进量达到5300万千瓦的目标。然而，大规模引入光伏将在电力系统中引起剩余电力等几个问题。我们需要大容量的抽水蓄能或蓄电池来储存多余的电力，但这些工厂的建设成本非常高。另一方面，在运输部门，电动汽车（EV）作为一种环保汽车正在开发中。为了促进电动汽车的普及，有必要建立能够在短时间内为电动汽车充电的基础设施，电池开关站是解决这一问题的方法之一。在车站，自动化开关平台将用充满电的电池替换耗尽的电池。耗尽的电池被放置在一个存储室和充电，以提供给其他司机。这意味着开关站始终具有恒定的电池容量。我们提出了使用站的电池作为对策的剩余电力的光伏发电和评估的经济价值所提出的系统。我们假设全国电力系统引进光伏5300万kW，并考虑了两种应对措施：（1）抽水蓄能;（2）电站蓄电池。泵壳和电池壳之间的年度总成本差异为6957亿日元。因此，如果公用事业公司从低于6，957亿日元的发电站租赁电池，则该公用事业公司将在电池案例中获得成本优势。
In the power sector, the Japanese government has set the goal of that the introduction of PV will reach 53 million kW by 2030. However, large-scale introduction of PV will cause several problems in power systems such as surplus electricity. We need large capacity of pumped storages or batteries for the surplus electricity, but the construction costs of these plants are very high. On the other hand, in the transport sector, Electric Vehicle (EV) is being developed as an environmentally friendly vehicle. To promote the diffusion of EV, it is necessary to build infrastructures that can charge EV in a short time; a battery switch station is one of the solutions to this problem. At a station, the automated switch platform will replace the depleted battery with a fully-charged battery. The depleted battery is placed in a storage room and recharged to be available to other drivers. This means switch stations always have the constant capacity of battery. We propose the use of station's batteries as a countermeasure for surplus electricity of PV and evaluate the economic value of the proposed system. We assumed that 53 million kW of PV is introduced in the nationwide power system and considered two countermeasures for surplus electricity: (1) Pumped storage; (2) Battery of station. The difference in total annual cost between Pumped case and Battery case results in 695.7 billion yen. Hence, if a utility leases batteries from stations fewer than 695.7 billion yen, the utility will get a cost advantage in Battery case.
