POWER SOURCE SYSTEM, POWER SUPPLY MANAGEMENT DEVICE, POWER SUPPLY MANAGEMENT METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To effectively use power generated by a power generation device.SOLUTION: A power source system of the present invention comprises: a power generation device for supplying generated power to a commercial power system; a DC power source device connected to the commercial power system and a power storage device connected to the DC side of the DC power source device; a load device that receives power supply from the commercial power system, the power generation device, and the power storage device; and a power supply management device for controlling charging/discharging operation of the power storage device by controlling output voltage from the DC power source device. The power supply management device comprises a voltage control unit for: setting a first voltage value that is a value of voltage set on the basis of a surplus power generation amount corresponding to a consumption amount to be consumed by the load device of a power generation amount generated by the power generation device and is lower than a second voltage value, which is a value of output voltage from the power storage device in a fully charged state; and setting, in making the power storage device discharge electricity, a setting voltage value for the output voltage from the DC power source device to the first voltage value.SELECTED DRAWING: Figure 1
