Abstract

As the number of Battery Electric Vehicle (BEV) is increasing dramatically Vehicle-to-Grid (V2G) te chnology also has been spotlight from industry and academia recently. With help of V2G technology Battery of EV can play many important roles like as energy storage system (ESS) and electric energy resource in Smart Grid environment. This paper provides comprehensive review of Vehicle-to-Home(V2H), Vehicle-to-Building(V2B) and Vehicle-to-Grid(V2G) technologies. The economical analysis of these technologies is also discussed.

급격한 전기자동차의 증가에 따라 전기자동차의 배터리를 주행 목적이 아닌 다른 용도로 사용하려는 Vehicle-to-Grid (V2G) 기술 또한 산업계와 학계부터 큰 관심을 끌고 있다. V2G 기술의 도움으로 전기자동차의 배터리는 스마트 그리드 환경에서 에너지 저장장치, 전력공급원등의 여러 중요한 역할로의 사용이 가능해 진다. 본고 에서는 거주용 주택환경을 위한 기술인 Vehicle-to-Home(V2H), 상업용 건물을 위한 기술인 Vehicle-to-Building(V2B) 그리고 전체 전력망을 위한 기술인 Vehicle-to-Grid(V2G) 기술에 대해 자세히 알아보고 각 기술의 특성과 영향에 대해 검토한다. 또한 이 기술들의 경제적 영향에 대해서도 분석한다.
