Abstract
The volume of the fuel transported from Japan to the Showa Base has been increasing year by year. In order to reduce the fuel consumption, a microgrid is considered in this work, namely Showa Base Microgrid (SBMG). giving the conditions of the optimization (System A) which was adapted for the random research of the many-variables problem nonlinear as the analysis method which used the simple genetic algorithm (GA) in the employment plan of SBMG in this paper, and the quantity control of a dispersed power source dynamo, The optimization (System B) which limited the search range of GA was proposed. As a result, We found the optimum operation of SBMG be installed in Showa base by examining the fossil fuel consumption.
