Title: Frequency regulation from renewable energy and storage systems

Abstract:  Power systems are transitioning to a scenario where renewable energy generation has a more important role. Many countries, such as the United States of America or the European Union countries, have taken on the challenge to increase the use of renewable energy to percentages around 20-30% in the next decades. This is very important due to environmental pollution or the depletion of fossil fuels; however, it creates several technical concerns such as the relative reduction of system inertia and possibly the appearance of larger frequency excursions. This presentation describes the general aspects of frequency regulation in power systems and how renewable energy generation and storage systems can participate in this challenging regulation task.

Bio:  Hector A. Pulgar obtained his Ph.D. degree in Electrical Engineering from the University of Illinois at Urbana-Champaign. From August 2001 to June 2014 he worked as professor at the Federico Santa Maria Technical University in Chile, where he taught about 14 different courses of the electrical engineering curriculum and obtained several research projects. In July 2014, he joined the Department of Electrical Engineering & Computer Sciences at the University of Tennessee, Knoxville as an Assistant Professor. His research activities are in the areas of power system dynamics, power system operation, power system stability and wind power generation.
