摘要:

本文针对预防性发电机检修调度(GMS)这一保障电力系统可靠性与效率的关键问题,对六种不同的混合整数规划(MIP)模型进行了全面理论分析。通过比较其线性松弛的紧性,识别出具有更优对偶界和更好计算性能的模型。分析通过定义、引理和命题建立模型间关系,证明部分模型松弛更紧,优化结果更高效。研究结果为从业者和研究者选择有效模型以改进预防性发电机检修调度过程提供了宝贵见解。

英文摘要:

This paper presents a comprehensive theoretical analysis of six distinct Mixed-Integer Programming (MIP) formulations for preventive Generator Maintenance Scheduling (GMS), a critical problem for ensuring the reliability and efficiency of power systems. By comparing the tightness of their linear relaxations, we identify which formulations offer superior dual bound and, thus, better computational performance. Our analysis includes establishing relationships between the formulations through definitions, lemmas, and propositions, demonstrating that some formulations provide tighter relaxations that lead to more efficient optimization outcomes. These findings offer valuable insights for practitioners and researchers in selecting the most effective models to enhance the scheduling process of preventive generator maintenance.
