Abstract

본고에서는 Advanced Metering Infrastructure (AMI) 네트워크 기반의 자동 수요반응 기술에 대해 소개한다. 수요반응은 피크 수요 기간 동안 전력의 안정화에 큰 기여를 할 수 있으며, 수요반응의 범위와 효과가 증가함에 따라 일반 수용가의 참여가 매우 중요한 이슈로 떠오르고 있다. 하지만, 다양한 지역에 위치한 수용가를 대상으로 수요반응 서비스를 제공하기 위해서는 유틸리티 또는 수요관리사업자와 고객 간의 수요반응 신호 교환과 정보 공유를 위한 통합 네트워크 구축이 필수적으로 필요하다. 또한, 이기종 시스템 간 상호운용성 보장을 위한 공통의 통신 제어 기술이 요구된다. 본고에서는 AMI 네트워크를 기반으로 IEC/PAS 규격인 Open Automated Demand Response version 2.0 (OpenADR2.0) 기술을 채택하여 수용가를 대상으로 한 자동화된 수요반응 서비스를 실현하고자 한다. AMI 디바이스를 수요반응 자원으로 활용하기 위하여 기존의 기능은 유지한 채로 OpenADR2.0 프로토콜을 탑재하여 수요반응 기능이 추가된 디바이스들을 개발하였으며, 프로토콜 적합성 테스트와 필드 테스트를 통하여 자동화된 수요 반응 서비스 및 부하 감축을 검증하였다. 개발 소프트웨어는 OpenADR Alliance로부터 국제공인인증을 획득함으로써 수요 반응 시스템의 레퍼런스 통신 기술로 적용이 가능하다.
