<P>PROBLEM TO BE SOLVED: To provide a method of determining the output capacity range of a power unit arranged in a high dispersibility state, in an electric power system that includes a voltage regulation device. <P>SOLUTION: Calculating the gross output capacity of a largest distributed power source 8 that satisfies restriction conditions in all points of a distribution system on the basis of a line-current profile and a line-voltage profile is to decide the total output capacity range of the distributed power source 8. Specifically, the line-current profile and the line-voltage profile in the predetermined total output capacity are calculated and it is judged whether all the restriction conditions are satisfied or not, taking notice of a maximum value of the line-current profile and the maximum and minimum values of the line-voltage profile. When all the restriction conditions are satisfied, the total output capacity of the distributed power source 8 is increased and the same calculations are repeated until either one of the restriction conditions is not satisfied to obtain the maximum value of the total output capacity of the distributed power source 8. <P>COPYRIGHT: (C)2007,JPO&INPIT |
