这项研究的目的是将广域同步测量和灵活交流输电系统(FACTS)相结合，以改善电力系统的动态控制。弗吉尼亚理工大学和密苏里大学罗拉分校的团队将利用相量测量单位和北美电网频率监测网络提供的广域信息，开发一个改善FACTS协调的框架。具体地说，这项工作将关联FACTS设备的可观性和可控性，开发FACTS设备和监视器的协调控制和放置方法，并分析在大规模系统验证时信号完整性的影响。智力优势：这项工作将超越目前仅使用少量设备仅使用本地信号的控制方法。整合适当选择的全局信息将最大限度地减少负面控制设备相互作用的可能性，同时改善区域间振荡缓解。使用实际测量来测试控制算法是另一个独特的功能，它将使开发的理论和算法更接近实际实施。基于广域测量的FACTS控制为改善电力系统的运行和控制方式提供了机会。广泛的影响：这项工作将有助于为应对系统故障的创新对策奠定基础，并有助于提高我国关键电力系统基础设施的可靠性。合作团队培育的研究环境将为培养新一代工程师提供机会，他们不仅拥有理论技能、动手经验、团队合作经验，而且还具有全球化思维的能力。

The objective of this research is to integrate synchronized wide area measurements and Flexible AC Transmission Systems (FACTS) to improve power system dynamic control. The Virginia Tech and University of Missouri-Rolla team will develop a framework for improved FACTS coordination utilizing wide area information provided by Phasor Measurement Units and the North America Power Grid Frequency Monitoring Network. Specifically, this work will correlate the observability and controllability for FACTS devices and develop coordinated control and placement approaches for FACTS devices and monitors, and analyze the impact of signal integrity when validating on a large scale system.Intellectual Merit:This effort will go beyond current approaches of control utilizing a small number of devices using only local signals. Integrating properly chosen global information will minimize the potential for negative control device interactions while simultaneously improving inter-area oscillation mitigation. The use of the actual measurements to test the control algorithms is another unique feature that will bring the theories and algorithms developed closer to actual implementation. The wide area measurements based FACTS control provides an opportunity to improve the manner in which power systems are operated and controlled.Broader Impact:This work will help lay the foundation for innovative counter-measures against system failures, and contribute to increased reliability of our nation's critical electric power system infrastructure. The research environment fostered by the collaborating team will provide opportunity to educate a new generation of engineers who will not only have the skills in theory, hands on experience, team work experience, but also the ability to think "globally".
