月度发输电检修一体优化方法

摘要

This paper presents an integrated generation and transmission monthly maintenance scheduling model and a decomposition-coordination algorithm. The optimization objective is to meet the maintenance requirements as much as possible, which is further transformed into an equivalent wish curve. The maintenance scheduling is decomposed and coordinated based on effective decision variables identification. The analysis and discussions on the results of numerical examples validate the feasibility and effectiveness of the model and algorithm.%文中建立了月度检修计划的发输电一体优化决策模型,提出了高效的分解协调算法.模型的优化目标旨在最大化满足设备的检修需求,并将其转化为等效的检修意愿成本曲线;通过精准辨识起作用的决策变量,实现了发输电检修计划的分解协调计算,有效地降低了问题求解规模,避免了算法振荡.采用多个算例验证了模型与算法的可行性与高效性.
