Abstract

The 'NIST Framework and Road Map for Smart Grid Interoperability Standards' proposes an architecture framework to secure the direction of development and standard interoperability of smart grid and provides a list of identified standard, standard cyber security strategies, and certification framework. In particular, SEP 2.0 and OpenADR 2.0 are the examples. SEP 2.0 and OpenADR 2.0 can functionally link HEMS and Smart Grid, but interoperability standards between the two protocols are not planned in above document. The OpenADR Alliance also announced that work is underway to define mapping tables for interoperability between OpenADR 2.0 and SEP 2.0, but no information is yet available. Therefore, In this paper, in developing energy efficiency improvement HEMS, we propose a mapping model that supports syntactic and semantic founded interoperability between SEP 2.0 and OpenADR 2.0b for ICT grid convergence based on the standard specification document of each protocol and confirmed through an example of the semantic mapping function based on the demand response service scenario.

'NIST framework and road map for smart grid interoperability standards' 기술 보고서는 스마트 그리드의 발전 방향, 표준의 상호운용성을 확보하는 아키텍처 프레임워크를 제시하고, 식별된 표준 리스트, 사이버 보안 전략, 시험 인증 프레임 워크를 제공하는 문서이다. 특히, 스마트 그리드의 표준 프로토콜인 SEP 2.0과 OpenADR 2.0이 그 예이다. SEP 2.0과 OpenADR 2.0은 기능적으로 HEMS와 스마트 그리드를 이어주는 역할을 할 수 있지만, 두 프로토콜 간에 상호운용 표준은 상기 문서에서 계획된 바가 없다. 또한, OpenADR 연합에서는 OpenADR 2.0과 SEP 2.0간의 상호운용을 위한 매핑 테이블을 정의하는 작업이 진행 중이라 발표했지만, 아직 공개한 정보는 없다. 따라서 본 논문에서는 신재생 에너지 효율 개선 HEMS 개발에 있어 ICT 전력 융합을 위한 SEP 2.0과 OpenADR 2.0b간의 상호운용을 각 프로토콜의 표준 사양 문서 기반의 구문과 의미로 대응하는 매핑 모델을 제안 하고 수요 반응 서비스 시나리오 기반의 의미 매핑 기능 예제를 통해 이를 확인하였다.
