Grid Converters for Photovoltaic and Wind Power Systems 

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

Institute of Technology, Aalborg University, teaching courses in
power electronics and electrical energy system control for masters
and Ph D students. He has authored over 80 journal and conference
papers, and one book Power Electronics: Computer Simulations
(Technical Press Budapest, 1997), and also holds 3 patents. He is
the founder and coordinator of the Green Power Laboratory at
Aalborg University, focusing on the development and testing of grid
converters for renewable energy systems, and is also co-recipient
of the Technical Committee Prize Paper Awards at IEEE IAS Annual
Meeting 1998, and IEEE Optim 2002. His research interests are in
the design and control of power converters used in renewable energy
systems, distributed generation, computer simulations and digital
control implementation.

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.
