<p><P>PROBLEM TO BE SOLVED: To reduce fluctuation in the amounts of electric power sold to a power system by multiple photovoltaic power generators. <P>SOLUTION: Each of the photovoltaic power generators 40A, 40B, 40C includes: a solar battery 1A; a storage battery 3A; a communication interface 30A for communication; and a battery control unit 20A for controlling power storage and power output to a power system. The battery control unit 20A of a first photovoltaic power generator 40A of the multiple photovoltaic power generators makes the first photovoltaic power generator 40A give a higher priority to power output to the power system than to power storage during a first period. Then it makes a second photovoltaic power generator 40B of the multiple photovoltaic power generators give a higher priority to power output to the power system than to power storage through the communication interface 30A during a second period with a predetermined delay to the first period. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
