<P>PROBLEM TO BE SOLVED: To prevent destabilization of a system due to excess power generated by a power generation system in the case a power generation device such as a photovoltaic power generation system will become dramatically and widely used. <P>SOLUTION: For example, in the case a power generation device is a solar cell panel, a power generation control system comprises: the solar cell panel 1; a power conditioner 2 for converting output of the panel into voltage able to execute system interconnection to a commercial alternative current power line; a communication slave unit 23 provided in the power conditioner 2 and able to extract a signal for power line communication from the power line; and a communication master unit 52 able to pour a signal for power line communication into a trunk power line of a transformer station 5. The power conditioner 2 has a function to avoid system interconnection on the basis of a control signal regarding permission or non-permission of system interconnection transmitted by the communication master unit 52 to the communication slave unit 23, and can restrain supply to the system of the power generated by photovoltaic generation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
