<p><P>PROBLEM TO BE SOLVED: To provide an output control system and control method for realizing an effective utilization of power for multiple photovoltaic generation devices linked to a commercial power system. <P>SOLUTION: An output control system for multiple distributed power sources includes the multiple distributed power sources linked to a commercial power system and also includes a management device. Each distributed power source comprises: a DC power source; a converter; a storage battery; a detecting unit for detecting a tolerable charge quantity of the storage battery and an output power value of the converter; a transmission unit and a reception unit for transmitting/receiving the tolerable charge quantity and the output power value; a first control unit for commanding a transmission of power-transmission/power-reception signals; and a second control unit for controlling a reverse power flow and charging. The management device comprises: a communication unit for performing a communication of power-transmission/power-reception signals with the distributed power sources; and a commanding unit for transmitting power-transmission/power-reception commands to the distributed power sources. When the tolerable charge quantity of a certain distributed power source is more than the output power value of other distributed power sources, the commanding unit transmits a command to start a power-reception to the certain distributed power source and a command to start a reverse power flow to other distributed power sources so that the certain distributed power source receives reversed power from the other distributed power sources. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
