초록

전기자동차를 이용하여 계통에 전력을 공급하는 Vehicle to Grid(V2G)의 구현을 위한 통신표준으로 ISO/IEC 15118이 적용되고 있다. 통신 프로토콜에 기반을 두는 전기자동차의 충방전 제어 시에 필연적으로 충방전 실행까지의 시간지연이 발생하게 되는데, 이러한 시간지연은 전력 유연성 공급 측면에서 제한의 요인이 된다. 본 연구에서는 ISO/IEC 15118 기반 V2G 에뮬레이터를 구현하고 전기 자동차 충방전 제어에 따른 반응성을 확인하였다. 실험결과 시간지연은 0.12ms로 나타났으며, 이를 기반으로 현 표준 하에서 참여 가능한 전력 유연성 시장에 대하여 검토하였다.

ISO/IEC 15118 is an international communication standard for EV(electric vehicle)'s V2G implementation. In the charging/discharging control of an EV based on a communication protocol, there is inevitably a time delay when charging/discharging occurs, and the delay may limit in supplying power flexibility. In this paper, we implemented an ISO/IEC 15118-based V2G emulator and measured the charge/discharge response characteristics. As a result, the time delay appeared as 0.12ms. Accordingly, the power flexibility markets that EV can participate in under the current standard were explored.
