Abstract

Wide-Area Power System Stabilizers (WAPSSs) are damping controllers used in power systems that employ data from Phasor Measurement Units (PMUs). WAPSSs are capable of providing high damping rates for the low-frequency oscillation modes, especially the inter-area modes. Oscillation modes can destabilize power systems if they are not correctly identified and adequately damped. However, WAPSS communication channels may be subject to failures or cyber-attacks that affect their proper operation and may even cause system instability. This research proposes a method based on an optimization model for the design of a WAPSS robust to multiple permanent communication failures. The results of applications of the proposed method in the IEEE 68-bus system show the ability of the WAPSS design to be robust to a possible number of permanent communication failures. Above this value, the combinations of failures and processing time are high and they make it difficult to obtain high damping rates for the closed-loop control system. The application and comparison of different optimization techniques are valid and showed a superior performance of the Grey Wolf Optimizer in solving the optimization problem.

一种能承受多重永久通信故障的广域电力系统稳定器的设计

广域电力系统稳定器(wapss)是电力系统中使用的阻尼控制器，它采用相量测量单元(pmu)的数据。wapss能够为低频振荡模式，特别是区域间振荡模式提供高阻尼率。振荡模态如果不能正确识别和充分阻尼，会使电力系统不稳定。但是，WAPSS通信通道可能会受到故障或网络攻击，影响其正常运行，甚至可能导致系统不稳定。本文提出了一种基于优化模型的WAPSS抗多次永久通信故障的设计方法。该方法在IEEE 68总线系统中的应用结果表明，WAPSS设计对可能出现的大量永久通信故障具有鲁棒性。在此值以上，故障和处理时间的组合很高，这使得闭环控制系统难以获得高阻尼率。通过对不同优化技术的应用和比较，证明了灰狼优化器在解决优化问题方面的优越性能。

期刊介绍： The Electricity Journal is the leading journal in electric power policy. The journal deals primarily with fuel diversity and the energy mix needed for optimal energy market performance, and therefore covers the full spectrum of energy, from coal, nuclear, natural gas and oil, to renewable energy sources including hydro, solar, geothermal and wind power. Recently, the journal has been publishing in emerging areas including energy storage, microgrid strategies, dynamic pricing, cyber security, climate change, cap and trade, distributed generation, net metering, transmission and generation market dynamics. The Electricity Journal aims to bring together the most thoughtful and influential thinkers globally from across industry, practitioners, government, policymakers and academia. The Editorial Advisory Board is comprised of electric industry thought leaders who have served as regulators, consultants, litigators, and market advocates. Their collective experience helps ensure that the most relevant and thought-provoking issues are presented to our readers, and helps navigate the emerging shape and design of the electricity/energy industry.
