互联多微电网联盟优化运行现状及展望

Current Status and Prospects of Optimized Operation of Interconnected Multi-microgrid Alliance

可再生资源的波动性和间歇性,发电机组的发电量及其负荷的时变性,以及能源交易过程中发电机组间能量的耦合等特点,都给电力系统的稳定运行和优化调度带来了新的挑战。为此分析了当前多微电网联盟中的能源管理体系;重点讨论了多微电网联盟拓扑结构、时间尺度和调度优化结构;解决了新能源就地消纳问题,降低了微网群整体碳排放量。结果表明,多微网联盟有助于构建新型电力系统,对未来电力系统的转型改革具有极大的推动促进作用。

The fluctuation and intermittence of renewable resources,the time variability of generating capacity and load of generator units,and the energy coupling between generator units in the process of energy trading have brought new challenges to the stable operation and optimal dispatching of power system.Therefore,the energy management system in the current multi-microgrid alliance was analyzed;the topology,time scale and scheduling optimization structure of the multi-microgrid alliance were focused on;the problem of local consumption of new energy was solved and the overall carbon emission of the microgrid cluster was reduced.The results show that the multi-microgrid alliance is helpful to build a new power system and plays a great role in promoting the transformation and reform of power system in the future.
