Talk Title: Distributed Power Electronics in Photovoltaic Power Systems
Series: Integrated Systems Seminar
Abstract: This talk is focused on power electronics in photovoltaic (PV) solar power systems. State of the art and emerging trends in PV system architectures are addressed, with emphasis on improvements in energy capture, efficiency, reliability, impact on reduced balance of system and installation costs, and increased levels of integration. Architectures based on distributed power electronics, including dc optimizers and microinverters, are highlighted. A new isolated-port system architecture is introduced, based on differential power processing submodule integrated dc-dc converters and simple distributed controls, leading to smart PV panels with integrated power management. It is shown how fine-granularity maximum power point tracking results in substantial improvements in energy capture in PV systems with mismatches due to partial shading, temperature gradients, dirt, tolerances, or ageing. Advantages of distributed differential power processing are verified by simulation and experimental results in representative scenarios, including rooftop and commercial-scale PV solar power systems.
Biography: Prof. Dragan Maksimovic received his Ph.D. degree from California Institute of Technology, Pasadena, in 1989. In 1992, he joined the University of Colorado at Boulder where he is currently a Charles V. Schelke Endowed Professor and Director of the Colorado Power Electronics Center (CoPEC) in the Department of Electrical, Computer and Energy Engineering. Prof. Maksimovic is a Fellow of the IEEE and serves as a Distinguished Lecturer of the IEEE Power Electronics Society. He is co-author of the textbook Fundamentals of Power Electronics, 2nd edition, Springer 2001. His current research interests include power electronics for renewable energy sources and energy efficiency, high frequency power conversion using wide bandgap semiconductors, digital control of switched-mode power converters, as well as analog, digital and mixed-signal integrated circuits for power management applications.
