具有复杂温度和需求不确定性的两阶段鲁棒机组组合问题

Two-Stage Robust Unit Commitment Problem with Complex Temperature and Demand Uncertainties

Wei Wang, Anna Danandeh, Brian Buckley, Bo Zeng

摘要:

在本文中,我们提出并研究了一个强大的机组组合模型和一些变种,考虑复杂的温度和需求的不确定性。由于在实际系统中,气体发生器的效率、需求和温度之间存在很强的关系,因此我们的鲁棒模型具有左侧和右侧(分别为LHS和RHS)的不确定性。与许多现有的鲁棒模型与RHS的不确定性,LHS的不确定性的引入带来了巨大的挑战,在计算鲁棒的解决方案。对于这些复杂的公式,我们分析它们的结构,推导出重要的属性,并设计精确和快速的近似解决方案的列和约束生成框架下的策略。在典型的IEEE测试系统上进行了数值实验,展示了我们的解决方案的巨大性能,并证明了系统操作中复杂和相关的不确定性的明显影响。

英文摘要:

In this paper, we present and study a robust unit commitment model and some variants that consider complex temperature and demand uncertainties. Since there is a strong relationship among the efficiency of gas generators, demand, and temperature in practical systems, our robust models have both left- and right-hand-side (LHS and RHS, respectively) uncertainties. Unlike many existing robust models with RHS uncertainty only, the introduction of LHS uncertainty imposes a huge challenge in computing robust solutions. For those complex formulations, we analyze their structures, derive important properties, and design exact and fast approximation solution strategies under the column-and-constraint generation framework. Numerical experiments are conducted on typical IEEE test systems, which showcase the great performance of our solution methods and demonstrate a clear impact of complex and correlated uncertainties in system operations.
