APPARATUS AND METHOD FOR OPERATING DISTRIBUTED GENERATOR IN CONNECTION WITH POWER SYSTEM

摘要

An apparatus for operating a distributed generator in connection with a power system includes an input unit which receives a parameter calculated using power system information and a voltage and a current at a point of common coupling with the distributed generator, with which the distributed generator is connected, a calculation unit which calculates an operating power factor instruction value and an active output instruction value using the parameter and the voltage and current at the point of common coupling with the distributed generator input to the input unit, and a control communication unit which determines and transmits the operating power factor instruction value and the active output instruction value according to the voltage at the point of common coupling with the distributed generator input to the input unit and an admissible voltage upper limit at the point of common coupling with the distributed generator to the distributed generator.
