소규모 제로에너지빌딩의 피크 수요관리용 EMS 운용 알고리즘에 관한 연구 = A Study on EMS Operation Algorithm for Peak Demand Management of Small Zero Energy Building

다국어 초록 (Multilingual Abstract)

Recently, the necessity of an EMS (energy management system) has increased since zero-energy buildings have been selected as the new energy industry according to the plan of the Korean government, which aims to reduce 37% of the estimated emissions of greenhouse gases in 2030. Although it is possible to install the BEMS (building energy management system) in new buildings according to the requirement of facility construction, in the case of the existing buildings, it is necessary to convert HMI or SCADA to BEMS or install a new EMS. Moreover, commercialized EMS tools adopt exclusive communication protocols of their own company or are operated with limited services because of poor communication compatibility with the equipment from other companies. This paper proposes the EMS operation algorithm for peak demand management in a zero energy building and implements the EMS for peak demand management, which is composed of communication devices, databases, and user interfaces. The simulation results confirmed that the proposed algorithm is a valuable tool because the discharge capacity of ESS can be reduced effectively in the SCADA system by comparing it with the existing operation method.

국문 초록 (Abstract)

최근, 정부의 2030년 온실가스 배출 전망치 대비 37%의 감축방안에 의하여, 제로에너지빌딩이 에너지신산업분야로 선정되어 EMS(energy management system)의 필요성이 증가하고 있다. 신축 건물에서는 BEMS(building energy management system)의 요구조건에 따라 설비시공이 가능하지만, 기존 건물의 경우 HMI 또는 SCADA를 BEMS로 전환하거나 새로운 EMS를 설치할 필요성이 있다. 또한, 상용화 EMS Tools의 경우 타사 장비와 통신 호환성이 원활하지 않아, 자사의 전용 통신 프로토콜을 적용한 제품을 사용하거나, 아니면 제한된 서비스만으로 운용하고 있다. 따라서, 본 논문에서는 범용 SCADA를 사용한 제로에너지빌딩의 피크 수요관리용 EMS의 운용 알고리즘을 제안하고, 통신장치, 데이터베이스, user interface로 구성된 피크 수요관리용 EMS를 구현한다. 이를 바탕으로 시뮬레이션을 수행한 결과, 범용 SCADA 환경에서 제안한 알고리즘을 적용하면 기존의 운용방식에 비해 ESS의 방전용량을 효과적으로 감소시킬 수 있어, 본 논문의 유용성을 확인하였다.
