基于奇异值优化的电力系统控制器整定

Controller tuning in power systems using singular value optimization

Amer Mešanović, Ulrich Münz, Rolf Findeisen

摘要:

随着可再生能源发电在大型电力系统中所占份额的不断增加,电力系统的运行变得越来越具有挑战性。可再生能源和传统发电的组合不断变化,导致动态发生很大变化,增加了停电的风险。我们建议重新调整电力系统中已经存在的控制器的参数,以应对看似变化的操作条件。为此,我们提出了一种快速和计算效率的结构控制器的参数调整的方法。调谐的目标是将系统极点移动到复平面中的指定区域,例如用于稳定或振荡阻尼。该方法利用频域中的奇异值优化,这使得能够扩展到大型系统,而不限于电力系统。该方法的效率上增加的大小与多个初始参数化的三个系统。

英文摘要:

As the share of renewable generation in large power systems continues to increase, the operation of power systems becomes increasingly challenging. The constantly shifting mix of renewable and conventional generation leads to largely changing dynamics, increasing the risk of blackouts. We propose to retune the parameters of the already present controllers in the power systems to account for the seemingly changing operating conditions. To this end, we present an approach for fast and computationally efficient tuning of parameters of structured controllers. The goal of the tuning is to shift system poles to a specified region in the complex plane, e.g. for stabilization or oscillation damping. The approach exploits singular value optimization in the frequency domain, which enables scaling to large systems and is not limited to power systems. The efficiency of the approach is shown on three systems of increasing size with multiple initial parameterizations.
