The invention discloses a subway train power flow peak clipping and valley filling method based on a train-train communication technology, which is based on a traditional four-section single-train energy-saving driving method and can effectively utilize an energy-saving slope in a coasting-constant speed combination mode to achieve the purpose of reducing energy consumption. Under the condition that given train set power flow is known, the multi-train collaborative optimization method for actual power flow absorption can absorb the power of the power grid as much as possible so as to achieve the effect of reducing grid side fluctuation peak clipping and valley filling. The wave crests and the wave troughs are partitioned, on the basis that power absorption is carried out as long as possible, the working condition conversion frequency of the train is reduced, and the comfort level of passengers is improved. According to the method, the train runs according to an off-line optimized driving strategy in the past and is optimized on line, so that the optimization efficiency is further improved.

    本发明公开了一种基于车车通信技术的地铁列车功率流的削峰填谷方法,本发明基于传统的四段式单车节能驾驶方法,采取惰行‑匀速组合方式能有效利用节能坡,达到减少能耗的目的。在已知已发出列车既定功率流的情况下,本发明针对实际功率流吸收的多车协同优化方法,能将电网的功率尽可能的吸收,以达到减少网侧波动削峰填谷的作用。本发明将波峰波谷分区间,在尽可能长时间的进行功率吸收的基础上,降低了列车的工况转换频次,增加了乘客舒适度。本发明将过去列车按照离线优化好的驾驶策略运行,转到在线优化上来,进一步提高优化的效率。
