POWER CONTROL DEVICE AND POWER CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To enable a power control device to effectively utilize electric power.SOLUTION: An index value acquisition section 130 finds an index value as the degree of electric power effective utilization when an in-operation number of power converters are placed in operation for each in-operation number of power converters. An in-operation number determination section 140 determines the in-operation number of power converters on the basis of the index value. An in-operation number determination section 140 can determines the number of power converters in operation that can effectively utilize electric power, so that the electric power can be effectively utilized.
