配電系統への燃料電池の最適配置計画に関する研究

A fuel cell has long been expected to be a very energy efficient and clean generation device and matured technologically to a stage of practical use. In consideration of its relatively small generating capacity, a fuel cell may be installed in a distribution network. In this paper, an optimal placement problem of fuel cells on a radial distribution network has been formulated as a mixed integer programming method and an efficient solution algorithm is proposed. The objective function to be minimized consists of electricity cost supplied by a substation, thermal cost by electricity, fixed and operating costs of fuel cells. In order to reduce search space, several constraints have been imposed such as possible locations and number of cells, voltage drops, and DSR (demand side reliability). The proposed algorithm has been tested on a 69 node radial system to obtain a solution within reasonable computation time.
