摘　　要：该文根据负荷连续变化的规律,针对若干个连续时间负荷段落,提出了多时间段落的配电网络动态重构的思想及方法。该方法以整个时区内节约的有功电量最大化或电源供给的电量最小化为优化目标,以整个时区内动作开关集中的单个开关的动作次数和所有开关的总动作次数小于相应的限值等为约束条件,并在此基础上通过适当的动态物理寻优策略去快速求得该问题的比较理想的可行解。因此,该方法完全摆脱了常规单时间断面配电网络静态重 构只能应用于规划领域的局限,它可以应用于配电网络的运行领域(如制定开关运行计划、在线调整开关运行方式等)。算例分析结果表明,通过连续动态重构,可以在较好地考虑动作开关的操作费用和减小网损之间关系的基础上快速获得整个时区内的开关动作表,为配电系统开关的日调度和在线预调度创造了条件。Basing on rule of continuous load profile, this paper proposes a new idea and its method of dynamic reconfiguration (DR) with multi-time periods in distribution network. DR can be solved by optimal problem. Objective function of DR can be the maximization of active energy savings or the minimization of active energy generated by sources during the whole time periods, constraints of DR can include operation numbers of some one switch and all switches in some sets, and et al. By using appropriate dynamic physical searching strategy, this paper can quickly obtains the relatively ideal solution. Hence, DR and its computation method completely overcome disadvantage of single-time-period static reconfiguration that can only be used in planning. DR can widely be used in operation, such as switch scheduling and online dispatching. Test systems show that continuous DR can schedule switches during the whole time periods with considering the relationship between switch operation cost and network loss reduction. Therefore, DR with high efficiencies supplies good conditions for off-line scheduling and on-line dispatching of switches in distribution network.
