The integration of new energy sources into the power grid is a rapidly evolving field, with a growing trend towards the use of power electronic converters. These converters, which differ significantly from conventional synchronous generators, offer high response speed and superior controllability. Their topology and control system can be flexibly structured to realize various functionalities, including resonance suppression, grid frequency support, and self-synchronization. This has led to the development of grid-friendly new energy systems and smarter, more flexible power grids. However, the versatility of power electronic converters also presents challenges in terms of stability and reliability. Their modeling, topology, and control are more complex and difficult to manage than those of conventional synchronous generators.

The primary objectives of this Research Topic are to inspire novel concepts and ideas related to the modeling, topology, and control technologies of power electronic converters, and to enhance their controllability and reliability. This will contribute to the development of smarter and more flexible modern power systems. The research aims to promote innovative findings, ideas, and breakthroughs in these fields, and welcomes applications papers.
