摘要

随着新能源和电力电子的发展,新型电力系统呈现典型的“双高”特征,但同时也带来低惯性、弱稳定性等问题。构网型（GFM）控制技术可实现变流器自主地建立频率和控制电压,改善对外部电压源的依赖性,提高系统稳定性。对构网型变流器的现状与发展趋势进行综述。首先,对跟网型（GFL）控制技术与构网型控制技术进行对比分析,指出构网型控制技术是解决新型电力系统稳定性的有效途径;然后介绍现有的构网型控制技术,分析构网型控制技术在各领域的应用;最后指出构网型控制技术应用于变流器时所面临的挑战。

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.
