Abstract

In this paper, the energy cost saving in multi-channel electric vehicle charging system. Joint use of the electric car charger battery state of charging proposed a method based charging. A linear programming with two type is used for optimal control, and the time-of-use price is included to calculate the energy costs. Simulation results show that the reductions of energy cost and peak power can be obtained using proposed method.

본 논문에서는 공용 사용목적으로 설치된 전기자동차 충전설비에 다수의 전기자동차가 충전시작과 종료시간이 정해진 조건에서 전력피크 제어와 전기자동차 충전 비용을 최소화 할 수 있는 전기자동차 충전시스템 제어방법을 제안하였다. 전기자동차 충전 과금정책으로 사용되는 계시별요금제기반에서 전기자동차 충전요금 절감할 수 있는 방법으로 전기자동차 배터리 충전상태를 제약조건으로 설정하고 선형계획법 알고리즘을 이용하여 전기자동차 충전시스템을 제어하는 방법을 사용하였다. 컴퓨터 시뮬레이션을 수행 하였을 때 기존 전기자동차 충전시스템보다 충전요금이 절감됨을 확인할 수 있었다.
