<P>PROBLEM TO BE SOLVED: To select a power generation power factor of distributed power supply which is suitable for interconnection with a power distribution system. <P>SOLUTION: In a power generation power factor selecting system of the distributed power supply which selects the power generation power factor of the distributed power supply connected to a distribution line, the system includes a generating portion, a predicting portion, a discriminating portion and a selecting portion. The generating portion generates a plurality of combined information which associates magnitude of a load connected to the distribution line with a plurality of generated outputs of the distributed power supply, with regard to each of a plurality of the power generation power factors of the distributed power supply. The predicting portion predicts a voltage value generated at predetermined points of the distribution line, based on the information, wherein the voltage value is generated when the distributed power supply related to each of a plurality of the combined information is connected to the distribution line. The discriminating portion discriminates whether the voltage value is a value within a predetermined range. The selecting portion selects the power generation power factor for the combined information in which the number of the generated outputs is maximum, as the power generation power factor of the distributed power supply, of the combined information which is discriminated by the predicting portion that the voltage value is the value within the predetermined range. <P>COPYRIGHT: (C)2008,JPO&INPIT |
