About the Author: Dr. Sudipta Chakraborty received the B.E. degree in electrical engineering from Bengal Engineering College (now Bengal Engineering and Science University), Shibpur, India, in 2001, and the Ph.D. degree in engineering systems, electrical specialty, from Colorado School of Mines, Golden, in 2007. He joined the National Renewable Energy Laboratory (NREL), a national laboratory of the U.S. Department of Energy (DOE), Golden, in 2007 where he is currently holds Senior Engineer position. His current research interests include development of advanced and modular power converters for renewable and distributed energy resources, development and testing of new smart grid modeling and hardware-in-loop validation techniques. His other specialty areas include power electronics and control for microgrid systems; inverter and hybrid vehicle grid integration testing; control and optimization (classical, neural network, fuzzy logic); variable frequency drives; and active filtering. Dr. Chakraborty is currently serving in IEEE-IES technical committees on power electronics and renewable energy systems. He has worked as one of the guest editor for the IEEE transaction on industrial electronics, special section on renewable energy systems. He is the contributing author of two published software copyrights on power electronics algorithms. Eight other intellectual properties developed by him on PV inverter hardware and software are currently under NREL-DOE review for future patents and copyright applications.
Dr. Marcelo G. Simões received a BS and MS from University of São Paulo, Brazil, and a Ph.D. from The University of Tennessee, USA, in 1985, 1990, and 1995, respectively, and his D. Sc. degree
(Livre-Docência) from the University of São Paulo in 1998. He is Associate Professor with Colorado School of Mines, where he has been establishing research and education activities in the development of intelligent control for high-power-electronics applications in renewable- and distributed energy systems. He is currently the Chair for the IEEE IES Smartgrid Committee. He has been involved in activities related to the control and management of smartgrid applications since 2002 with his NSF CAREER award "Intelligent Based Performance Enhancement Control of Micropower Energy Systems." He has co-authored the books Renewable Energy Systems: Design and Analysis with Induction Generators (CRC Press) and Integration of Alternative Sources of Energy (Wiley/IEEE Press).
Dr. William E. Kramer's current research includes and the development of integrated systems and controls for smart grid and vehicle technologies including new control and visualization techniques for Man in the Loop Controls, advanced power electronics, controls, supervisory control systems. He received his Masters and Bachelor of Science degree from Kansas State University with a focus on optimization, adaptive, digital control systems and numerical simulation methods for the integration of electrical and mechanical systems. In his current position at the Department of Energy's National Renewable Energy Laboratory, Bill is the principal engineer and technical advisor for energy systems integration Projects at DOE's new Energy Systems Integration Facility. During his tenure as a Research Associate and PhD candidate at Colorado State University, he assisted in the management the DOE Energy Analysis and Development Center, developed electrical and control systems for a ground up solar car that competed in the first GM Sunrayce, he partnered with Motorola to for the development of a radio modem for remote control and data collection for vehicle applications and lead a team to design and retrofit a ford vehicle for competition at the Ford Hybrid Electric Vehicle Challenge Project.
