<P>PROBLEM TO BE SOLVED: To reduce a difference of facility utilization factors between distributed power supplies in a distribution system and a difference between power selling incomes, and to suppress the deterioration of the energy utilization efficiency of the power supply in the distribution system as whole. <P>SOLUTION: This voltage control method calculates voltage sensitivity with respect to the change amount of active power from the change amount of active power at a tie point between a distribution line and the distributed power supply B and the change amount of a voltage, and when the voltage sensitivity is not higher than a threshold for determining whether aid by an output of inactive power should be performed or not, the voltage control method determines that the other distributed power supply A is shifted to voltage-rise suppression control, and makes the distributed power supply B start the aid by the output of the inactive power. <P>COPYRIGHT: (C)2007,JPO&INPIT |
