To make it possible to create an optimal solution in a short time by shifting each of an arbitrary number of looped switches, including a switch of interest from a closed state to an open state to create a plurality of candidates of system configuration, and determining a power system configuration based on the candidates.
Equipment of interest is let be A1, and one branch switch B1 is turned on in order to create a loop containing the equipment A1. The switch C1 in one branch comprising the created loop is turned off to open the loop, and adjacent candidates are thereby created. For example, since a loop created by turning on one switch contains four branches, there are four branches that can be turned off. While equipment to look at is sequentially changed, transition to a system configuration which obtains an optimal evaluation function among the created adjacent states is repeated using the taboo search method. Thereby, an optimal solution for system configuration, such as that minimizing transmission loss, can be created in a short time.
