摘要： PROBLEM TO BE SOLVED: To suppress degradation in power quality accompanied by operating condition of a voltage source. SOLUTION: A target value is established by a controller 4 for the operating condition (for example, active power, reactive power) of a distributed power source 3 (voltage source). The operating condition (for example, active power, reactive power) is measured in the distributed power source 3 by the controller 4. The measured value of the operating condition in the distributed power source 3 (voltage source) is compared with the target value established by the controller 4, and the difference is calculated to vary the operating condition (for example, active power, reactive power) of a current source 1. The operating condition of the voltage source is conformed to the target value by varying the operating condition of the current source 1. COPYRIGHT: (C)2009,JPO&INPIT
