摘要

随着新能源与电力电子设备的高比例接入，新型电力系统面临惯量缺失、稳定性弱化等挑战。传统跟网型控制依赖电网电压支撑的并网模式，导致系统频率/电压调节能力不足，已引发多起稳定性事故，而构网型控制通过模拟同步机特性，使变流器具备自主构建电压/频率的能力，显著提升系统惯量响应和阻尼特性。基于此，首先，本文对储能变流器的拓扑进行简要介绍，探讨其在新能源并网中的应用潜力；其次，对于现有的跟网型变流器和构网型变流器进行对比总结分析并介绍现有构网控制技术；最后，指出构网型技术应用于变流器时所面临的难点以及对未来研究的展望。

Abstract

With the high proportion of new energy and power electronic devices connected to the grid

the new type of power system is facing such challenges as lack of inertia and weak stability. The traditional grid-following control relies on the grid connection mode of grid voltage support

resulting in insufficient system frequency/voltage regulation capacity

and leading to a number of stability accidents. However

the grid-forming control makes the converter possess the ability of constructing voltage /frequency independently by simulating the characteristics of synchronous machine

which significantly improves both system inertia response and damping characteristics. Based on this

firstly

the topology of the energy storage converter is briefly introduced and its potential application in new energy grid-connection is explored. Then

the existing grid-following converter and grid-forming converter are compared

analyzed and analyzed

and the existing grid-forming control technology is introduced. Finally

the difficulties encountered by the grid-forming technology in case of application to the converter and the outlook of the future research are pointed out.
