摘要:可入网电动汽车（plug-in electric vehicle，PEV）近年来发展迅猛，考虑PEV与清洁能源大量并网后的差异性需求，构建兼顾输电网、配电网与用户利益的双层规划模型。上层输电网规划以系统运行成本最小、车主消费最少、弃风弃光惩罚最少、碳排放总量最小为目标，协同调度火电机组、新能源与PEV出力，实现PEV的时域调度；下层配电网模型以网损最小为目标，通过最优潮流计算实现PEV的空间调度。算例结果表明，对PEV进行有效调度并配合合理的电网规划方案，可降低电网运行成本，提高其对可再生能源的消纳能力。

Abstract:In recent years，plug-in electric vehicle （PEV） has developed rapidly.Taking discrepant of the grid connected large number of PEV and clean energy into account，considering the interests of transmission grid，distribution grid and users，a bi-level programming model was proposed.The upper layer optimization in transmission grid aimed at minimizing system operation cost，vehicle owner consumption，wind and light curtailment penalty and total carbon emission，with collaborative scheduling thermal generators，new energy and PEV output，and PEV temporal dimension scheduling was realized；The lower layer optimization in distribution grid level aimed at minimizing the network loss and the PEV spatial dimension scheduling through the optimal power flow calculation was realized.Results of calculating example showed that the effective scheduling of PEV and reasonable power grid planning could reduce the operation cost of power grid and improve its ability to accommodate renewable energy.

Key words:PEV;bi-level optimization;distribution grid;grid programming
