PROBLEM TO BE SOLVED: To realize a 100% automatic operation of a power storage together with a distributed power supply in a power system stabilizer compensating the power fluctuation. SOLUTION: In a power system stabilizer which suppresses output fluctuation of a distributed power supply 11 to suppress the power system fluctuation by controlling the output of the power supply 11 together with a rechargeable power storage 13, a control device 18 is provided to sum up the output of the power supply averaged in a certain period and the dischargeable power from the storage 13 in a unit time within the dischargeable period when discharging the storage 13 connected to the power supply and regards it as the total output of the power supply 11 and the storage 13. When charging the storage 13 using the power supply, the control device 18 makes the total output power zero or regards the above sum the total power and updates the total output power for every certain period. |
