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.

Continuous cost reduction of photovoltaic (PV) systems and the rise of power auctions resulted in the establishment of PV power not only as a green energy source but also as a cost-effective solution to the electricity generation market. Various commercial solutions for grid-connected PV systems are available at any power level, ranging from multi-megawatt utility-scale solar farms to sub-kilowatt residential PV installations. Compared to utility-scale systems, the feasibility of small-scale residential PV installations is still limited by existing technologies that have not yet properly address issues like operation in weak grids, opaque and partial shading, etc. New market drivers such as warranty improvement to match the PV module lifespan, operation voltage range extension for application flexibility, and embedded energy storage for load shifting have again put small-scale PV systems in the spotlight. This Special Issue collects the latest developments in the field of power electronic converter topologies, control, design, and optimization for better energy yield, power conversion efficiency, reliability, and longer lifetime of the small-scale PV systems. This Special Issue will serve as a reference and update for academics, researchers, and practicing engineers to inspire new research and developments that pave the way for next-generation PV systems for residential and small commercial applications.
