摘要

针对大规模电动汽车网络中灵活的车对电网(V2G)支持,提出了一种双向恒速充电协调(BCCC)的充电方案。电动汽车集群和充电配置协调对V2G整体效益有重大影响,但由于电动汽车移动性的不确定性,这一问题一般难以解决。该方案通过固定充放电倍率,采用二进制整数线性规划(ILP)实现电动汽车或电动汽车充电站运行成本的最小化。BCCC还提供了V2G支持的电池磨损成本的简单估算,以告知电动汽车车主的净收益。在住宅综合体充电站的数值模拟中,50辆电动汽车共同协调以最小化净充电成本,其中BCCC比非协调的先到先得(FCFS)策略提供约50美元/天的收益。

Poster: Electric vehicle network bidirectional charging for flexible vehicle-to-grid services
For flexible vehicle-to-grid (V2G) supports with a large scale electric vehicle (EV) network, a novel charging scheme is proposed in this study with a bidirectional constant-rate charging coordination (BCCC). Clustering EVs and coordinating their charging profiles have significant impact on overall V2G benefits however it is difficult to solve in general due to the uncertainty in EVs' mobility. In the proposed scheme, minimizing the operation cost for EVs or EV charging stations can be formulated by the binary integer linear programming (ILP) by fixing the charging and discharging rates. BCCC also provides simple estimation of the battery wear cost from V2G supports, to inform the net benefit to EV owners. In numerical simulations for a residential complex charging station, 50 EVs are jointly coordinated to minimize the net charging costs, where BCCC provides ∼ 50$/day benefit over the uncoordinated first-come first-serve (FCFS) strategy.
