鲁棒AC最优潮流

Robust AC Optimal Power Flow

Raphael Louca, Eilyan Bitar

摘要:

越来越需要新的最优化方法来促进具有间歇性可再生能源的电力系统的可靠和成本有效的操作。本文将鲁棒交流最优潮流(RAC-OPF)问题转化为一个带补偿的两阶段鲁棒最优化问题。这个问题相当于一个非凸的无限维最优化问题,这是计算上棘手的,在一般情况下。假设在输电网络中的每个母线上都有可调的发电量或负荷,通过限制追索策略空间在不确定问题数据中的仿射性,我们开发了一种从有限维半定规划中近似RAC-OPF的技术。我们建立了一个充分条件,在此条件下,半定规划返回一个仿射补偿策略,保证原RAC-OPF问题是可行的。我们说明了所提出的最优化方法的有效性WSCC 9总线和IEEE 14总线测试系统与不同水平的可再生资源的渗透和不确定性。

英文摘要:

There is a growing need for new optimization methods to facilitate the reliable and cost-effective operation of power systems with intermittent renewable energy resources. In this paper, we formulate the robust AC optimal power flow (RAC-OPF) problem as a two-stage robust optimization problem with recourse. This problem amounts to a nonconvex infinite-dimensional optimization problem that is computationally intractable, in general. Under the assumption that there is adjustable generation or load at every bus in the power transmission network, we develop a technique to approximate RAC-OPF from within by a finite-dimensional semidefinite program by restricting the space of recourse policies to be affine in the uncertain problem data. We establish a sufficient condition under which the semidefinite program returns an affine recourse policy that is guaranteed to be feasible for the original RAC-OPF problem. We illustrate the effectiveness of the proposed optimization method on the WSCC 9-bus and IEEE 14-bus test systems with different levels of renewable resource penetration and uncertainty.
