摘要：构建"网-源-储-车"协同供电架构以实现电气化铁路的实时、可靠、高效能量管控,对推进"双碳"目标的实现具有重要意义.然而,既有规则管控策略主要针对"网-储-车"架构、管控,效果有限;优化管控策略往往关注于经济性等单一指标,可靠性较低.为此,该文首先补充了适用于"网-源-储-车"架构的规则管控策略,并构建了计及经济性与电压不平衡度的多目标管控优化模型;然后,提出一种基于"规则+优化"的电气化铁路站点实时能量管控策略,采用优化管控为主、规则管控为辅的形式,以实时管控时间阈值为导向,有序切换输出指令,在保证站点能量管控的可靠性与实时性的同时,实现整体运行效果的优化提升;最后,基于刘家沟牵引变电所实测数据对所提策略进行验证,结果表明,该文所提策略在实现新能源就地消纳与再生制动能量高效利用的同时,可改善牵引网电压水平与公共电网电能质量.
