Abstract

Energy Storage System(ESS) is a system that maximizes energy efficiency by selectively storing and using the generated power when needed. Therefore, energy must be able to be charged or supplied at any time, and non-operating time should be minimized even in the case of failure or maintenance. However, current large-capacity energy storage systems must be shut down during maintenance due to structural problems. In this paper, we propose a PCS for 1MW ESS by configuring modular for large capacity ESS in parallel and verified of the hot swap technology that can replace, change, and repair the components that make up the system while keeping the system operating.

에너지저장시스템(Energy Storage System)은 생산된 전력을 필요한 시기에 선택적으로 저장하고 사용함으로써 에너지 효율을 극대화 시키는 시스템이다. 따라서 언제든지 에너지를 충전하거나 공급할 수 있는 상태를 유지하여야 하며, 고장이나 유지보수 시에도 비운영 시간을 최소화하여야 한다. 하지만 현재 대용량 에너지저장시스템은 구조적 문제로 유지보수 시 반드시 운영을 정지하여야 한다. 본 논문에서는 대용량 에너지저장시스템용 모듈라(Modular)를 병렬 구성하여 1MW급 에너지저장시스템용 PCS를 제작하고, 시스템에서 동작 상태를 유지하면서 시스템을 구성하는 요소들의 교체, 변경, 수리가 가능한 핫스왑(Hot Swap) 기술을 실험을 통해 검증하였다.
