Modeling and Control of Power Electronics for Renewables

Modern power electronics converters are used in a wide range of applications, including switched-mode power supplies, electrical machine motion control, active power filters, and distributed power generation. Power electronics, an important interface between renewables and the grid, has advanced rapidly in recent years. As the percentage of renewables integration increases, new challenges emerge, such as weak grid issues, high-frequency circulation suppression, active grid support function, arc detection, and so on. These new issues create new challenges for modeling and controlling power electronics. As a result, in-depth discussions on these issues are required in order to provide technical support for the global energy transition. The purpose of this research topic is to investigate the modeling and control of power electronics converters, as well as to provide the reader with how to analyze and model converter behavior in order to improve their design and operation. Furthermore, a set of algorithms designed specifically for use with power converters to address emerging challenges such as weak grid issues, high-frequency circulation suppression, active grid support function, arc detection, and so on. We hope that this Research Topic will provide an overview of the state-of-the-art in modeling and controlling power electronics for renewable energy and power systems.
