DISTRIBUTED POWER SUPPLY FACILITY SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve entire operation efficiency so as to also suppress increase of a cooperation point voltage in the case where a plurality of distributed power supply facilities are cooperated with a low-voltage single-phase distribution line at one cooperation point.SOLUTION: Several power computers 12 among a plurality of distributed power supply facilities 14 are power computers with reactive power regulation functions each including a function for outputting reactive power, and power computers of the remaining distributed power supply facilities are normal power computers with no reactive power regulation function. Any one of the power computers with the reactive power regulation functions outputs reactive power and the power computers of the remaining distributed power supply facilities output only active power. Each of the power computers determines whether a cooperation point voltage exceeds a predetermined value in accordance with increase of active power. Among the power computers, the power computer with the reactive power regulation function outputting the active power successively outputs reactive power so as to prevent the cooperation point voltage from exceeding the predetermined value in the case where it is predicted that the cooperation point voltage may exceed the predetermined value.
