본문

본 논문은 태양광, 풍력발전, 연료전지 시스템 등의 계통연계 분산 전원시스템에서 계통 임피던스 추정을 이용한 계통연계 인버터의

제어기 이득 조정 기법을 제안한다. 제안된 기법에 사용된 계통임피던스 추정 방법은 계통연계 인버터 출력측의 유효전력과 무효

전력량을 순시 적으로 변화시킨다. 전력에 순시적인 변화를 주는 동안 발생되는 두 개의 동작 점에서 측정된 전압, 전류 값을

기반으로 계통 측 임피던스를 추정한다. 추정된 계통임피던스를 이용한 제어기 이득 조정 기법을 통해 제어기의 안정성을 보장한다.

시뮬레이션을 통해 제안한 알고리즘의 성능을 검증한다.
