To address the global climate crisis

achieving energy transitions is imperative. Establishing a new-type power system is a key measure to achieve CO

emissions peaking and carbon neutrality. The core goal is to transform renewable energy resources into primary power sources. The large-scale integration of high proportions of renewable energy sources and power electronic devices will dramatically change the operational mechanisms and control strategies of power systems. Existing wind and solar converters mostly adopt the grid-following control mode

which leads to significant challenges in system security and stability as it is insufficient to support the frequency and voltage of the grid. On the other hand

grid- forming control technology (GFM) can provide voltage and frequency support for the system

and thus becomes an effective measure to improve the inertia and damping characteristics of power systems. This paper illustrates the principles

control strategies

equipment types

application scenarios

and project implementation of grid-forming technology. The simulation and

analysis based on a renewable-dominated real new-type power system show that GFM can significantly enhance the frequency and voltage support capacity of the power system

improve renewable energy accommodation capacity and grid transmission capacity under weak grid conditions

and play an important role in enhancing the stability and power supply reliability of renewable-dominated new-type power systems.
