研究了配电馈线在系统日常运行中的电容器调度问题。目标是根据第二天的预测小时负荷，达到最佳的电容器调度计划，从而使一天中的总馈线损耗最小化。必须考虑的约束条件包括每个电容器每天允许的最大开关操作次数，以及馈线上的电压限制。提出了一种基于动态规划的优化调度方法。为验证此方法的有效性，以台湾电力公司台北西区办事处服务区内的配电馈线电容器调度为研究对象。结果表明，最优电容器调度比固定调度能更有效地降低电力系统的损耗。
The dispatch of capacitors on a distribution feeder in daily system operation is investigated. The objective is to reach an optimal capacitor dispatching schedule, based on the forecast hourly loads for the next day, such that the total feeder loss in a day is minimised. The constraints that must be taken into account include the maximum allowable number of switching operations in a day for each capacitor, and the voltage limits on the feeder. An approach based on dynamic programming is presented to reach such an optimal schedule. To demonstrate the effectiveness of the proposed approach, the dispatch of capacitors on a distribution feeder within the service area of Taipei West District Office of Taiwan Power Company is investigated. It is concluded that a greater loss reduction can be achieved by the optimal capacitor dispatch than by the fixed-schedule dispatch.
