Abstract

Low-frequency oscillations with insufficient damping can compromise the integrity of power systems. Various control mechanisms exist to mitigate these oscillations, with Wide Area Damping Controllers (WADC) being notably efficient by utilizing remote signals captured by Phasor Measurement Units. A primary challenge in developing a WADC framework is the latency associated with transmitting these remote signals. This challenge is exacerbated by uncertainties, making deterministic methods for WADC tuning potentially impractical. This study introduces an optimization methodology for the probabilistic design of a WADC that accounts for uncertainties in power loads and signal transmission delays. This methodology incorporates the likelihood of meeting security and stability criteria as constraints and employs Particle Swarm Optimization and Unscented Transformation for problem resolution. The efficacy of the proposed method is demonstrated through its application to a Brazilian test system, highlighting its promising results in terms of precision and computational efficiency compared to the Monte Carlo simulation.

基于Unscented变换的广域阻尼控制器概率设计方法

阻尼不足的低频振荡会危及电力系统的完整性。存在各种控制机制来减轻这些振荡，广域阻尼控制器（WADC）通过利用相量测量单元捕获的远程信号显着高效。开发WADC框架的主要挑战是与传输这些远程信号相关的延迟。不确定性加剧了这一挑战，使得WADC调优的确定性方法可能不切实际。本研究介绍了一种WADC概率设计的优化方法，该方法考虑了功率负载和信号传输延迟的不确定性。该方法将满足安全性和稳定性标准的可能性作为约束，并采用粒子群优化和无气味变换来解决问题。通过对巴西测试系统的应用，证明了该方法的有效性，与蒙特卡罗模拟相比，该方法在精度和计算效率方面取得了令人满意的结果。
