스마트그리드는 전력 에너지의 공급과 소비가 양방향으로 이루어지며, 인터넷 기술을 사용하여 실시간으로 전력 정보를 제공하므로 피크 전력을 감소시키면서 에너지 절약 및 효율적인 에너지 사용을 가능하게 한다. 최근 계속되는 국내의 전력난을 해결하기 위해 신규 발전소의 건립과 같은 발전 공급 설비 증대를 통한 해결 방안보다는, 기존 전력량의 효율적인 사용과 배전단과 소비자단에서 분산 신재생 에너지와 에너지 전력저장 장치의 효율적인 활용을 위해 정보통신기술(ICT)을 기반으로 실시간 모니터링과 제어를 가능하게 하는 AMI(Advanced Metering Infrastructure)의 중요성이 강조되고 있다. 본 고에서는 국내외 스마트그리드 기술 현황과 스마트그리드 서비스 제공의 근간이 되는 AMI를 위한 네트워크 구조 및 사용되는 통신 기술을 살펴보았다.
