U.S.-Germany Cooperative Research on the Dynamic Security Analysis of Electric Power Systems

该奖项支持亚利桑那州立大学的Anjan Bose教授和研究生与德国多特蒙德大学的Edmund Handschin教授及其研究团队在电气工程研究方面的合作。他们合作的主题是电力系统的动态安全分析。这两个小组都积极参与电力工程这一重要的新领域的研究，但他们带来了不同的优势和不同的研究方法。例如，在并行处理领域，亚利桑那小组专注于寻找能够在可用的多处理器上运行的并行算法，而德国小组则在寻找解决动态方程的最佳并行架构。这两家公司都参与了电力系统控制中心最坏情况应急筛选工具的开发。在这个领域，亚利桑那小组专注于更快的分析方法，尽管不太准确，而德国小组正在开发比分析方法更准确的专家系统，但在其他方面受到更多限制。合作的一个主要目标是在这些方法之间找到平衡，从而优化动态分析。对大型互联输电网和发电电网的持续在线安全评估是一个非常重要的复杂问题，北美和西欧都遭受了区域性停电，造成了严重的经济后果。电网的安全性在于其承受突发干扰或突发事件的能力。然而，目前的技术水平假设系统在任何干扰下都能稳定运行，因为对动态波动运行进行实际建模所需的计算不能足够快地完成在线运行。正在进行的美德研究由该奖项协助，重点是解决这一动态安全分析问题。

This award supports Professor Anjan Bose and a graduate student of Arizona State University to collaborate in electrical engineering research with Professor Edmund Handschin and his research team at the University of Dortmund, Germany. The subject of their collaboration is the dynamic security analysis of electric power systems. Both groups are actively involved in research in this important new area of electric power engineering, but they bring different strengths and different research approaches to the problem. For example, in the area of parallel processing, the Arizona group is concentrating on finding parallel algorithms that will operate on available multiprocessors, while the German group is seeking the best parallel architecture to solve the dynamic equations. Both are involved in the development of worst case contingency screening tools for power system control centers. In this area, the Arizona group has concentrated on faster, though less accurate, analytical methods while the German group is developing expert systems that are more accurate than analytical methods but more limited in other ways. A major objective of the collaboration is to find a balance between these approaches that will optimize dynamic analysis. The continual on-line assessment of security of the large interconnected power transmission and generation grid is a complex problem of great importance to North America and Western Europe, both of which have suffered regional blackouts that have had serious economic consequences. The security of the electric power network lies in its ability to withstand unexpected disturbances or contingencies. Yet current state of the art assumes stable operation of the system during any disturbance, because calculations required for realistic modeling of a dynamic, fluctuating operation cannot be done fast enough for on-line operation. The ongoing U.S.-German research assisted by this award focuses on solving this dynamic security analysis problem.
