本研究的目的是通过在并网双馈感应发电风电场中集成阻尼器来提高电力系统区域间振荡的阻尼力。该方法是采用两个转子控制回路，允许独立调节有功功率和无功功率，同时提供减振效益。智力优势：该项目解决了电力系统中的稳定性增强问题，因为风电场中的存在和独特的挑战越来越多。重点在于通过风电场有功/无功调制的新概念来开发稳健的阻尼控制器，以帮助缓解整个互联电力系统中的不稳定问题。如果电网互联系统配备了这样的控制器，该项目还将有助于传达增强稳定性的良性影响。更广泛的影响：该项目将有助于减少风电场电网整合的一些障碍。如果成功，这项研究将促进大规模风力发电进入现有电网。加强风能资源的整合将减少化石燃料对发电的依赖，从而造福社会，从而有助于建立可持续的能源基础设施。该教育计划将把研究成果与关于可再生系统建模/大规模电力系统动力学的研究生课程结合起来，并继续为研究生研究招聘合格的女学生。该项目将有助于消除人们对电网互联电力系统稳定性的一些怀疑。总体而言，这些活动将有助于促进和发展中西部地区和全国的风能资源。

The objective of this research is to improve the damping of inter-area oscillations in power systems by integrating damping controllers in grid-connected doubly-fed induction-generator-based wind farms. The approach is to employ two rotor control loops that allow independent modulation of active and reactive powers while providing damping benefits.Intellectual Merits: This project addresses the problem of stability enhancements in power systems, given the increasing presence of and unique challenges in wind farms. The focus lies in developing robust damping controllers through a novel concept of real/reactive power modulation in wind farms to help mitigate instability concerns in the overall interconnected power system. The project will also help convey the benign effects of stability enhancements if grid interconnected systems are equipped with such controllers. Broader Impacts: The project will help reduce some of the barriers to grid integration of wind farms. If successful, the research will facilitate penetration of large scale wind power into the existing grid. Increased integration of wind resources will benefit society by reducing fossil fuel dependence on electricity generation and thus help build a sustainable energy infrastructure. The educational plan will integrate research results with graduate courses on renewable systems modeling /bulk power system dynamics and continue the recruitment of qualified female students for graduate research. This project will help resolve some of the skepticism surrounding the stability of grid interconnected power systems. Overall, the activities will help promote and develop wind resources in the midwest region and the nation at large.
