Abstract

In this paper we present a decomposition approach based on duality theory for line maintenance scheduling with transmission and voltage constraints. The given formulation consists of a master program and sub-problems with two independent programs. In the master problem, the maintenance problem is solved and in the subproblems, transmission and voltage problems are solved independently. Since cancelling a transaction or purchasing reactive power relates to the loss of revenue, the trade-off between maintenance cost and revenue loss is be optimized in the proposed method. The test results on the modified IEEE 118-bus system demonstrate that limits on transmission and voltage affect the line maintenance scheduling and increase the maintenance cost. While introducing the loss of revenue as one of the objective functions, the proposed method is flexible enough to accommodate various pricing objectives and methods.

解除管制系统中的短期输电线路维护调度

本文提出了一种基于对偶理论的线路维护调度分解方法。给定的公式由一个主规划和两个独立规划的子问题组成。在主问题中，解决了维护问题，在子问题中，分别解决了传输和电压问题。由于取消交易或购买无功功率涉及收益损失，因此该方法优化了维护成本与收益损失之间的权衡。在改进的IEEE 118总线系统上的测试结果表明，传输和电压的限制影响了线路维护计划，增加了维护成本。在引入收入损失作为目标函数的同时，该方法具有足够的灵活性，可以适应不同的定价目标和方法。
