Disclosed are a system and a method for controlling charging and discharging electric vehicles in a micro grid with blockchain-based energy trading. In particular, the method for controlling charging and discharging electric vehicles comprises the steps of: once a first electric vehicle is connected to an electric vehicle station, generating energy trading request information of the first electric vehicle on the basis of battery information and driving information of the first electric vehicle; trading virtual money with a second electric vehicle which is matched in energy trading through the electric vehicle station according to the energy trading request information of the first electric vehicle; according to the content of the energy trading, charging the first electric vehicle with energy discharged by the second electric vehicle, or discharging, from the first electric vehicle to the electric vehicle station, energy for charging the second electric vehicle; and sending a trading statement of the virtual money and an energy charging-discharging statement to all electric vehicles connected to the electric vehicle station and the electric vehicle station, to be approved, wherein the second electric vehicle can be one of a plurality of electric vehicles that has been connected to the electric vehicle station before the first electric vehicle is connected to the electric vehicle station.

    블록체인 기반 에너지 거래에 따른 마이크로그리드에서의 전기차 충방전 제어 시스템 및 방법이 개시된다. 전기차의 충전/방전 제어 방법은 제1 전기차가 전기차 스테이션에 연결되면, 상기 제1 전기차의 배터리 정보 및 주행 정보에 기초하여 상기 제1 전기차의 에너지 거래 요청 정보를 생성하는 단계; 상기 제1 전기차의 에너지 거래 요청 정보에 따라 상기 전기차 스테이션을 통하여 에너지 거래가 매칭된 제2 전기차와 가상 화폐를 거래하는 단계; 상기 에너지 거래의 내용에 따라 상기 제2 전기차가 방전한 에너지로 상기 제1 전기차를 충전하거나, 상기 제2 전기차를 충전하기 위한 에너지를 상기 제1 전기차에서 상기 전기차 스테이션으로 방전하는 단계; 및 상기 가상 화폐의 거래 내역 및 에너지의 충전/방전 내역을 상기 전기차 스테이션에 연결된 모든 전기차들 및 상기 전기차 스테이션에 전송하여 승인받는 단계를 포함하고, 상기 제2 전기차는, 상기 제1 전기차가 상기 전기차 스테이션에 연결되기 전에 상기 전기차 스테이션에 연결되어 있던 복수의 전기차들 중 하나일 수 있다.
