Abstract

The supply of renewable energy has become more vigorous due to Paris Agreement. In Korea, supply policies of renewable energy is being promoted with priority given to public buildings, so, the supply of fuel cell system that are relatively easy to install in buildings is expected to expand, so it is important that study on anti-islanding evaluation of grid-connected power conditioning system(PCS) for fuel cell. In this study, we consider that KGS AB934 PC53 in domestic certification standard of PCS for fuel cell correspond with abroad standard and analyze anti-islanding evaluation that important safety performance when connected grid. Additionally, we constructed a prototype for anti-islanding evaluation of PCS for fuel cell connected in parallel and carried out the demonstration evaluation, so, we have conducted ways that ensure safety performance in accordance with the circumstances where several fuel cell systems are installed.

파리협정의 체결로 신 재생에너지 보급이 활발해지고 있다. 국내의 경우 공공건물 중심으로 신 재재생에너지 보급 정책이 진행되고 있으며, 건물 내에 설치가 비교적 수월한 연료전지 시스템의 보급이 확대될 전망이여서 계통연계형 연료전지 전력변환장치의 단독운전방지 평가 연구가 중요하다. 본 연구에서는 연료전지 전력변환장치의 국내 인증기준 KGS AB934 PC53이 해외 규격과 부합하는지 검토해보고 계통연계 시 중요한 안전성능인 단독운전방지 평가에 대해 분석하였다. 또한, 병렬로 연결된 두 대의 전력변환장치의 단독운전방지 평가를 위한 시작품을 제작하고 실증 평가를 통해 여러 대의 연료전지 시스템이 설치되고 있는 상황에 맞는 안전성능 확보 방안을 연구하였다.
