POWER MANAGEMENT DEVICE, POWER MANAGEMENT SYSTEM, AND POWER MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a power management device capable of alleviating disadvantages of a user in a case where an output of a distributed power source is suppressed to a suppression power threshold or lower, a power management system and a power management method.SOLUTION: A PCS 130 performs a compensation control of increasing an output of a solar cell 110 so that the output of the solar cell 110 exceeds a suppression power threshold when a storage battery 120 is charged with an output of the solar cell 110 in a totalization period.SELECTED DRAWING: Figure 2
