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.

本研究的目的是改善阻尼的区域间振荡的电力系统中，通过集成阻尼控制器的并网双馈感应发电机为基础的风力发电场。该方法是采用两个转子控制回路，允许独立调制的有功和无功功率，同时提供dampingbenefits.Intellectual优点：该项目解决了在电力系统中的稳定性增强的问题，考虑到风电场的日益存在和独特的挑战。重点在于通过风电场的真实的/无功功率调制的新概念来开发鲁棒阻尼控制器，以帮助减轻整个互联电力系统的不稳定性问题。该项目还将有助于传达稳定性增强的良性影响，如果电网互联系统配备了这样的控制器。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，该研究将促进大规模风电进入现有电网。增加风能资源的整合将减少对化石燃料发电的依赖，从而有利于社会，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可再生系统建模/大容量电力系统动力学的研究生课程结合起来，并继续招收合格的女学生进行研究生研究。该项目将有助于解决围绕电网互联电力系统稳定性的一些怀疑。总的来说，这些活动将有助于促进和开发中西部地区和全国的风力资源。
