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 (PV) and Storage Battery (BT), mainly for residential customers. Especially focusing attention on BTs, 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 of the storage battery is not taken into consideration, although the electricity charge increases, it is evaluated that the system can be used stably for a long time. Also, in a system that combines PV and BT, DC power bus (DC Bus) is controlled to a constant value for the purpose of supplying electric power to DC load and stable power supply to AC load.

In this paper, a novel optimization tool is developed for a customer including new devices which are photovoltaic power generation (PV) and storage battery (BT). A treatment of thermal constraints of BT is introduced in the formulation for energy management system (EMS). Especially, thermal constraints are important to achieve the stable operation of demand-side energy system. The authors carry out the operation planning simulation by using nonlinear programming method. In latter section, a real-time simulation tool for the EMS is introduced by using MATLAB/Simulink SimPowerSystems.
