主动配电网的日前-日内两阶段优化调度

针对主动配电网的日前-日内两阶段优化调度问题，首先构建了配电管理系统总揽全局、区域调控终端负责分区的调控框架。采用经济性与安全性协调统一的两阶段调度策略:日前执行经济调度，降低主动配电网(active distribution network，ADN)运行成本；日内阶段正常时各子区域跟踪日前计划进行分区局部修正，存在电压越限时DMS执行系统全局调整以消除越限。建立了日前经济调度、日内分区局部功率修正与系统全局电压调整的数学优化模型，并采用和声搜索算法来求解调度模型。最后通过算例分析，验证了所提调度方法能够适用于日前-日内两个阶段，保障ADN经济安全运行。

Day-ahead and Intraday Two-stage Optimal Dispatch of Active Distribution Network

The day-ahead and intraday optimal dispatch problems of active distribution network are studied. Firstly, the dispatch and control framework that DMS controls overall situation meanwhile regional dispatch and control terminals regulate local regions is constructed. A two-stage dispatch strategy coordinating economy and security is adopted. Day-ahead economic scheduling is carried out to reduce active distribution network (ADN) operation cost. In intraday stage, normally each region tracks day-ahead scheduling and implements the regional dispatch correction. When voltage violation occurs, distribution management system performs the global adjustment to eliminate the violation. Mathematical optimization models with day-ahead economic dispatch, intraday regional power correction and global voltage adjustment are established. Harmony search algorithm is applied to solve the dispatch model. Finally, a case is studied to verify that the proposed approach can be applied to solve two-stage dispatch and ensure the economic and secure operation of ADN.
