<P>PROBLEM TO BE SOLVED: To provide a generating set that can easily be introduced into a cogeneration system small in scale and having no reverse power flow, and is operated so as to maximally exhibit an economic effect. <P>SOLUTION: The generating set is connected to an in-plant system that is interlinked to a commercial system at an interlinkage point without the reverse power flow, and feeds generated power to the in-plant system so that received power at the interlinkage point coincides with a received power constant control set value. In the generating set, a received power amount at an arbitrary point in a demand time limit is integrated from a demand time-limit start to that time point to obtain the received power amount, a demand prediction value at a demand time-limit terminating time point is predicted from the present received power amount and the received power amount at the arbitrary time point, a received power control adjusting value is obtained by subtracting the demand prediction value from a target set value, a new received power constant control set value is obtained by adding the received power control adjusting value to the received power constant control set value at the arbitrary time point, and the generated power is controlled so that the received power coincides with the obtained new received power constant control set value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
