摘要：

With the increasing penetration of renewable energy and power electronic equipment, the inertia and the system strength of power system have decreased greatly, resulting in more serious stability issues. Grid-forming (GFM) control technology can improve voltage and frequency regulation capacity of converters, so as to improve power system stability. This paper presents an overview of the current state and development trends of GFM control. First, the differences between GFM control technology and grid-following (GFL) control technology are compared, and four types of GFM control strategies are introduced. Next, the function of GFM control in power system is analyzed, and some specific application scenarios are introduced. Finally, research challenges and hopeful solutions of GFM technology are discussed. © 2022 Power System Technology Press. All rights reserved.
