摘要

为降低电力系统中风电出力波动、低频振荡和多控制器耦合等因素带来的危害,提出一种多运行方式下多控制器参数协调优化策略。首先,基于Simulink建立风光火打捆外送系统和控制器模型,通过Voronoi分区采样法建立风电典型出力场景。然后,利用概率论方法构造优化问题目标函数,通过随机森林回归分析选取控制器关键优化参数。最后,采用改进的混合蜣螂算法对多运行方式下的控制器关键参数进行协调优化设计。IEEE 4机2区和16机5区系统仿真结果表明,对提取出来的控制器参数进行优化,能有效提高系统阻尼,抑制低频振荡引起的系统有功、功角等的波动,验证该概率优化方法的有效性。

Abstract

To mitigate the adverse effects of wind power output fluctuations, low-frequency oscillations, and multi-controller coupling in power systems, this paper proposes a coordinated optimization strategy for multi-controller parameters under diverse operating conditions. Firstly, a Simulink model of the wind-PV-thermal bundled power transmission system and its controllers is established. Typical wind power output scenarios are generated using the Voronoi partition sampling method. Subsequently, the objective function for the optimization problem is formulated based on probabilistic methods, and critical controller parameters for optimization are identified via random forest regression analysis. Finally, an improved hybrid dung beetle optimizer is employed to coordinately optimize these key controller parameters across multiple operating scenarios. Simulation results on the IEEE 4-machine 2-area system and the 16-machine 5-area system demonstrate that optimizing the extracted controller parameters effectively enhances system damping. This significantly suppresses fluctuations in active power, power angles, and other system variables caused by low-frequency oscillations, thereby validating the efficacy of the proposed probabilistic optimization approach.
