论文摘要
本文旨在实施和评估量子计算的性能,以解决由电网运营引起的解决组合优化问题。为此,我们构建了一种新型的混合整数圆锥编程公式,以响应分布线的故障来重新配置径向分布网络。与文献中现有的总线注入模型相比,我们基于公式的分支流模型在理论上是等效的,而无需不可解释的变量,因此在数值上更稳定。然后,将网络重新配置模型用作评估实际量子计算机中量子计算算法的性能的基准。它表明,尽管在量子计算机中具有快速执行时间的当前量子计算算法可能是有前途的解决方案候选者,但在应用于电网优化问题时,应仔细考虑其启发式性质。
This paper aims to implement and evaluate the performance of quantum computing on solving combinatorial optimization problems arising from the operations of the power grid. To this end, we construct a novel mixed integer conic programming formulation for the reconfiguration of radial distribution network in response to faults in distribution lines. Comparing to existing bus injection model in the literature, our formulation based the branch flows model is theoretically equivalent without needing non-explainable variables, thus being more numerically stable. The network reconfiguration model is then used as a benchmark to evaluate the performance of quantum computing algorithms in real quantum computers. It shows that while current quantum computing algorithms with fast execution time in quantum computers can be a promising solution candidate, its heuristic nature stem from its theoretical foundation should be considered carefully when applying into power grid optimization problems.
