Abstract

In this paper, we propose the automatic demand response systems which reduce the electric power consumption for the period automatically distinct from the existing passive demand response that a subscriber directly controls the energy consumption. The proposed systems are based on SEP 2.0 and consist of the demand response management program, the demand response server, and the demand response client. The demand response program shows the current status of the electric power use to a subscriber and supports the function which the administrator enables to creates or cancels a demand response event. The demand response server transmits the demand response event received from the demand response management program to the demand response client through SEP 2.0 protocol, and it stores the metering data from the demand response client in a database. After extracting the data, such as the demand response the start time, the duration, the reduction level, the demand response client reduces the electric power consumption for the period.

본 논문에서는 기존의 가입자가 직접 전력량을 조절하는 수동수요반응과는 달리 정해진 시간에 자동적으로 전력량 소모를 줄이는 자동수요반응 시스템을 제안하였다. 제안된 시스템은 SEP 2.0을 기반으로 동작하며 수요반응 관리 프로그램과 수요반응 서버, 수요반응 클라이언트로 구성된다. 수요반응 관리 프로그램은 가입자에게 전력사용현황을 알려주고 관리자에게는 수요반응 이벤트를 생성 및 취소할 수 있게 한다. 수요반응 서버는 수요반응 관리 프로그램에서 수신한 수요반응 이벤트를 SEP 2.0을 통해 수요반응 클라이언트로 전송하고 수요반응 클라이언트가 주기적으로 전송하는 미터링 데이터를 데이터베이스에 저장한다. 그리고 수요반응 클라이언트는 수신한 수요반응 이벤트에서 수요반응 이벤트 시작시간과 지속시간, 감소레벨을 추출한 뒤, 특정 기간 동안 전력소모를 감소시킨다.
