摘要(Abstract)：

含不同类型能源的局域电网中包括多个微网,在微网内部引入电转气P2G(powertogas)设备加强了电力和天然气网络间的耦合,减少了弃水弃光现象,但也使可再生能源在进行优化调度时发生了能源重复转换,降低了用能效率,产生能源损耗。同时,随着越来越多的微网在一定区域的聚合形成了多微网系统,其存在着微网与配网和微网间的功率交互。在此背景下,基于目标级联法,依据利益主体的不同,以生产效益最优为目标,建立了一种考虑微网内部能源重复转换,微网与配网、微网间功率交互的优化调度模型,该模型计及了对各设备出力的影响,优化得到了协调各设备的调度运行计划及系统最优运行成本。最后,在算例中对模型进行验证,结果表明所提优化调度模型能够在提高可再生能源消纳的情况下,降低系统运行成本,提高用能效率,实现了整个系统的能量优化管理。
