SUMMARY:Vortrag von Prof. Lucy Y. Pao
DESCRIPTION:\nProf. Lucy Y. Pao\n Department of Electrical, Computer, and Energy Engineering\n University of Colorado, Boulder\n \n\n\n \n\n\n\nTuesday 2015-06-02 11:00\n IST-Seminar-Room V2.268 - Pfaffenwaldring 9 - Campus Stuttgart-Vaihingen Room V2.268 -\nPfaffenwaldring 9  \nAbstract\nWind energy is recognized worldwide as cost-effective and environmentally friendly and is among\nthe world's fastest-growing sources of electrical energy. Despite the amazing growth in global wind\npower installations in recent years, science and engineering challenges still exist. It is commonly\nreported that the variability of wind is a major obstacle to integrating large amounts of wind\nenergy on the utility grid. Wind's variability creates challenges because power supply and demand\nmust match in order to maintain a constant grid frequency. As wind energy penetration increases to\nhigher levels in many countries, however, systems and control techniques can be used to actively\ncontrol the power generated by wind turbines and wind farms to help regulate the grid frequency. In\nthis talk, we will first provide an overview of wind energy systems by introducing the primary\nstructural components and operating regions of wind turbines. The operation of the utility grid\nwill be outlined by discussing the electrical system, explaining the importance of preserving grid\nreliability through controlling the grid frequency (which is a measure of the balance between\nelectrical generation and load), and describing the methods of providing ancillary services for\nfrequency support using conventional generation utilities. We will then discuss how wind turbines\nand wind farms can be controlled to help stabilize and balance the frequency of the utility grid.\nResults of simulation studies as well as experimental field tests will be presented to show the\npromise of the techniques being developed. We shall close by discussing continuing challenges and\nfuture research avenues that can facilitate the widespread adoption of active power control\nservices provided by wind farms, and how advanced distributed capabilities can reduce the\nintegration cost of wind energy and enable much higher wind energy penetrations while\nsimultaneously maintaining and possibly increasing the reliability of the utility grid.\nBiographical Information\nLucy Pao is currently a Professor in the Electrical, Computer, and Energy Engineering Department\nand a Professor (by courtesy) in the Aerospace Engineering Sciences Department at the University of\nColorado Boulder. She earned B.S., M.S., and Ph.D. degrees in Electrical Engineering from Stanford\nUniversity. Her research has primarily been in the control systems area, with applications ranging\nfrom atomic force microscopy to disk drives to digital tape drives to megawatt wind turbines and\nwind farms. Selected recent and current professional society activities include being General Chair\nfor the 2013 American Control Conference, an IEEE Control Systems Society (CSS) Distinguished\nLecturer (2008-present), a member of the IEEE CSS Board of Governors (2011-2013 (elected) and 2015\n(appointed)), and a Fellow of the Renewable and Sustainable Energy Institute (2009-present).\nSelected recent honors include elevation to IEEE Fellow in 2012, the 2012 IEEE Control Systems\nMagazine Outstanding Paper Award, and election to Fellow of the International Federation of\nAutomatic Control (IFAC) in 2013.
