In this paper, we show the result of building and simulating a model that can optimally operate electric power supply by a system combining photovoltaic power generation and storage battery. Especially focusing attention on storage batteries, by solving the objective function that minimizes electricity charges of customers by using the internal temperature and life characteristics of the storage battery as constraint conditions, an optimal solution is obtained. Compared with the case where the constraint condition is not taken into consideration, although the electricity charge increases, it is evaluated that the system can be used stably for a long time.
