Abstract

With the development of new energy and power electronics, new power systems exhibit typical "dual high" characteristics, but at the same time, they also bring problems such as low inertia and weak stability. Grid forming control technology （GFM） can enable the inverter to independently establish frequency and control voltage, improve dependence on external voltage sources, and improve system stability. The current situation and development trend of grid type converters are summarized. Firstly, a comparative analysis was conducted between grid following control technology （GFL） and grid building control technology, and it was pointed out that grid building control technology is an effective way to solve the stability of new power systems. Then, the existing grid control technology was introduced, and the application of grid control technology in various fields were analyzed. Finally, the challenges faced when applying grid control technology to converters were pointed out.
