Improving Power Balance Using PEV Charging and Discharging Scheduling in Microgrid

Abstract

In this paper, a scheduling of the V2G is proposed for valley filling and cost-effectiveness evaluation. The PEVs are divided into three groups depending on the connecting period of the PEVs. The standard deviation of the difference between with and without PEVs are measured. The results show that valley filling has been improved by using proper V2G scheduling proposed in this paper.|본 논문에서는 충전 중인 차량도 방전에 참여를 시키는 알고리즘을 제안한다. 휴리스틱 분기한정법(Branch and Bound)를 적용한 전기차 충/방전 스케줄링에서는 계통 내 수요와 공급의 편차를 최소로 하고, 전기차 방전을 최대로 하는 목적함수를 적용한다. 제안된 스케줄링으로 인해 전력균형이 12.2% 개선되었고, 방전량은 40% 증가된 결과를 도출하였다.; In this paper, a scheduling of the V2G is proposed for valley filling and cost-effectiveness evaluation.
