摘要:

本文讨论一种本质上去中心化的内点法,该方法非常适合能源网络中出现的优化问题。所提方法的优势在于:即使对于具有非凸约束的问题,也能保证快速局部收敛。此外,我们的方法通信开销小,并且能在有限迭代次数内达到相对较高的求解精度,同时局部子问题的计算复杂度较低。我们通过一个能源系统问题来展示所提方法的性能,即考虑一个具有708个节点的最优潮流问题。

英文摘要:

This note discusses an essentially decentralized interior point method, which is well suited for optimization problems arising in energy networks. Advantages of the proposed method are guaranteed and fast local convergence also for problems with non-convex constraints. Moreover, our method exhibits a small communication footprint and it achieves a comparably high solution accuracy with a limited number of iterations, whereby the local subproblems are of low computational complexity. We illustrate the performance of the proposed method on a problem from energy systems, i.e., we consider an optimal power flow problem with 708 buses.
