본 발명의 계통 안정화 장치는 전기차와 충전기를 연결하는 충전 케이블과, 전력계통의 전력 데이터를 수집하는 전력 측정부, 급속 또는 완속 충전을 위해 전기차 내부와 충전기 간의 통신을 제어하는 전기차 통신제어모듈과 통신 연결되며, 데이터를 주고받는 충전기 통신제어 모듈, 전기차와 충전기를 포함하는 분산부하와 전력계통 간의 전력 전송시 발생되는 불안정에 대한 계통 보호 조치를 취하는 계통 보호부를 포함할 수 있고, 전기차에 탑재되는 전력 변환부의 전력변환이 정상 동작하지 않는 경우, 상기 계통 보호부는 전력계통에서 불안정이 발생되지 않도록 전기차 또는 충전기의 방전 중단이나 역전송 중단을 명령할 수 있다.

    A grid stabilization device of the present invention may comprise: a charging cable which connects an electric vehicle and a charger; a power measurement unit which collects power data of a power grid; a charger communication control module which is connected, through communication, to an electric vehicle communication control module for controlling communication between the inside of the electric vehicle and the charger for fast or slow charging and exchanges data therewith; and a grid protection unit that takes a grid protection measure against instability generated when power is transmitted between the power grid and a distributed load including the electric vehicle and the charger, wherein when power conversion of a power conversion unit mounted on the electric vehicle does not normally operate, the grid protection unit may command the electric vehicle or the charger to stop discharging or reverse transmission so that instability does not occur in the power grid.
