Abstract
We have developed control system for micro-grid in which a battery compensates fluctuation by solar generation and electrical load. This paper describes an evaluation of control parameters (compensated band, output's initial value) for battery control to obtain peak demand reduction by the micro-grid. We show that by applying this method, amount of peak demand reduction has little influence of prediction error and reliability of this method is verified by two kinds of demand profiles in summer and winter. These results show that the method has applicability to the micro-grid operation.
