<P>PROBLEM TO BE SOLVED: To provide a power system management system and a management method for a power system capable of reducing suppression of the power generation amount by distribution type power supplies even when voltage deviation occurs, while avoiding the occurrence of the voltage deviation as much as possible, in the power system where a large number of the distribution type power supplies are interconnected. <P>SOLUTION: A voltmeter measures each power reception voltage of a user of each power distribution feeder line. A control device: collects measured voltage measurement values; makes a power distribution transformer change transmission voltage so that a first voltage which is the highest voltage value is to be the highest within a range no more than a predetermined upper limit, when the difference between the first voltage and a second voltage which is the lowest voltage value is lower than a preset threshold; and makes the power distribution transformer change the transmission voltage so that the second voltage is to be the lowest within a range no less than a predetermined lower limit, when the difference of the first voltage and the second voltage is larger than the threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT |
