论文摘要
鉴于AC网络和设备约束，交替流动的最佳功率流（AC-OPF）被构架为NP-固定的非凸优化问题，该问题解决了网格生成的最经济性发电和设备约束。尽管没有用于获得该问题全球最优的标准方法，但计划和运营工程师在寻找本地最佳的情况下引起了极大的兴趣。尽管如此，解决大型AC-OPF问题的本地最佳问题是具有挑战性且耗时的，因为没有领先的非线性优化工具箱可以提供任何及时保证融合的保证。为了为大型复杂系统提供强大的局部收敛性，我们引入了一种基于同型的方法，该方法解决了一系列原始的双重内部点问题。我们利用网格的物理学来开发提出的同型方法，并证明了这种方法对美国东部互连大小的测试网络的功效。
Alternating-Current Optimal Power Flow (AC-OPF) is framed as a NP-hard non-convex optimization problem that solves for the most economical dispatch of grid generation given the AC-network and device constraints. Although there are no standard methodologies for obtaining the global optimum for the problem, there is considerable interest from planning and operational engineers in finding a local optimum. Nonetheless, solving for the local optima of a large AC-OPF problem is challenging and time-intensive, as none of the leading non-linear optimization toolboxes can provide any timely guarantees of convergence. To provide robust local convergence for large complex systems, we introduce a homotopy-based approach that solves a sequence of primal-dual interior point problems. We utilize the physics of the grid to develop the proposed homotopy method and demonstrate the efficacy of this approach on U.S. Eastern Interconnection sized test networks.
