互联多微电网联盟优化运行现状及展望

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。

Optimal Batching Structures of Single Machine Scheduling

A batch is a subset of jobs which must be processed jointly in either serial or parallel form. For the single machine, batching, total completion time scheduling problems, the algorithmic aspects have been extensively studied in the literature. This paper presents the optimal hatching structures of the problems on the batching ways： all jobs in exactly N（arbitrary fix batch number and 1 〈 N 〈 n） batches.
