Grid Converters for Photovoltaic and Wind Power Systems (IEEE Press)

Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support.

This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor.

With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues:

• modern grid inverter topologies for photovoltaic and wind turbines
• islanding detection methods for photovoltaic systems
• synchronization techniques based on second order generalized integrators (SOGI)
• advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques
• power control under grid fault conditions, considering both positive and negative sequences

Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry. For people from academia interested in adopting the course, a set of slides is available for download from the website. www.wiley.com/go/grid_converters

Marco Liserre is currently Assistant Professor at the Bari Polytechnic, Italy, teaching courses in basic and advanced power electronics, and industrial electronics. His research interests are in the control of power converters and drives, power quality, and distributed generation, and he has authored 70 papers on these subjects, 13 of them having been published in international journals. He has worked towards several projects funded by the Italian government and has also lectured at Aalborg University, Delft University, and at the Warsaw University of Technology. He is Editor of the Newsletter of the Industrial Electronic Society, and Associate Editor of the IEEE Transactions on Industrial Electronics.

Pedro Rodriguez received his M.S. and Ph.D. degrees in electrical engineering from the Technical University of Catalonia (UPC), Spain. He is currently an Associate Professor in the Electrical Engineering Department at the UPC, where he is the head of the Renewable Electrical Energy Systems (REES) center. He stayed as a researcher in the Department of Energy Technology (DET), at Aalborg University (Denmark), what resulted in close research collaboration. Currently, he is a regular Visiting Professor at the DET, where he participates as a co-supervisor in the Vestas Power Programme. His research activity lies on the field of electronic power processors applied to electrical distributed generation systems, being mainly focused on designing of controllers for the  grid interactive power processors, designing power electronics based power processors for green energy sources, and proposing new technical solutions to improve stability and power quality in electrical networks.
