摘要(Abstract):
换电站(batteryswappingstation,BSS)作为电动汽车能源供给的重要来源,在日常运营中欠缺对负荷换电完成程度的考虑。提出了电动汽车积压惩罚机制,并构建了BSS与含风电微电网结合的联合系统调度模型。积压惩罚机制充分考虑了系统调度策略对于换电完成程度的影响,并将BSS换电完成程度反馈给系统调度层从而生成更合理的充换电计划。该模型以系统运行成本最小化为目标函数,综合考虑了电池供给约束和换电站电池充电约束,并通过优化软件CPLEX求解该模型。最后,在某微网系统下,对系统孤网运行和并网运行两种方案进行对比分析,验证了系统并网运行方案的优越性。同时通过灵敏度分析表明,适当调整初始系统状态可减少系统运营成本,提高风电消纳。
