Grid Converters for Photovoltaic and Wind Power Systems

Advancements in grid converter technology have been pivotal in the successful integration of renewable energy. 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 current injection during faults, and 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, coverage focuses on the specific applications in photovoltaic and 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 relevant issues are discussed:

• 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
• Resonant controller techniques for current control and harmonic compensation
• Grid filter design and active damping techniques
• Power control under grid fault conditions, considering both positive and negative sequences

Throughout, the authors include practical examples, exercises, and simulation models and an accompanying website sets out further modeling techniques using MATLAB® and Simulink environments and physical security information management (PSIM) software.

Grid Converters for Photovoltaic and Wind Power Systems is intended as a course book for graduate students with a background in electrical engineering and for professionals in the evolving renewable energy industry. For professors interested in adopting the course, a set of slides is available for download from the website.
