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.

This paper proposes a new framework of distribution system planning under the condition of mass installed Distributed Generators (DGs). At present, distribution system planners do not pay much attention to the interconnection of DGs. However, if some DGs can supply power instead of conventional power stations, they will give a significant impact. The planners will have a new option to build a network system plan without unnecessary investment to distribution networks. In this study, an objective function for distribution system planning is formulated to obtain maximum profits for utilities, and the authors discuss reduction of the utilities' investment cost and distribution system loss for installation of DGs. In addition, the authors propose a solution method using a genetic algorithm technique in order to find quasi-optimal solutions for large scale problems. Furthermore, the authors also discuss the connection tariff in order to increase the utilization rate of distribution networks. The advantage of the proposed method is demonstrated through several numerical simulations with successful results.
