The invention discloses a scheduling method for electric buses participating in V2G, and the method comprises the steps: employing a double-layer optimization model at a day-ahead stage, taking the minimum daily operation cost of a bus company as a target at an upper layer, and employing an iterative method to achieve the linkage optimization of the battery loss cost and a charging and dischargingplan of a charging station; on the basis of the upper-layer optimization result, enabling the lower-layer model to further optimize the charging and discharging plan of the charging station by takingthe minimum peak-valley difference of the load of the power distribution network as the target, and performing rolling updating on photovoltaic output and basic load power of the power distribution network in the intra-day stage; and correcting the day-ahead plan by taking the minimum daily operation cost of a bus company and the minimum daily and intra-day plan deviation as targets. The method can reduce the peak-valley difference of the load of the power distribution network on the basis of improving the operation economy of a bus company, and is high in practicality.
本发明公开了一种电动公交车参与V2G的调度方法,日前阶段采用双层优化模型,上层以公交公司的日运营成本最小为目标,采用迭代法对电池损耗成本和充电站的充放电计划进行联动优化;下层模型在上层优化结果的基础上,以配电网负荷峰谷差最小为目标,进一步优化充电站的充放电计划,日内阶段对光伏出力和配电网基础负荷功率进行滚动更新,以公交公司日运营成本最小和日前、日内计划偏差最小为目标对日前计划进行修正。本发明可以在提高公交公司运营经济性的基础上,减小配电网负荷的峰谷差,实用性强。
