Virtual Inertia Control of the Virtual Synchronous Generator: A Review

Meiyi Li, Wentao Huang, Nengling Tai, Dongliang Duan

摘要:

随着分布式发电的普及,低惯量的影响越来越大,虚拟同步发电机(Virtual Synchronous Generator,VSG)技术被提出来,通过提供“虚拟惯量”来提高逆变器接口分布式发电机的稳定性。本文从物理和数学两个角度对虚拟惯性控制的意义、特点、设计原理和最新的惯性控制策略进行了综述,以促进虚拟惯性控制的广泛应用。给出了虚惯性的定义和来源,以帮助研究者建立“虚惯性”的概念。然后,本文对虚拟惯性的影响机理进行了研究,揭示了虚拟惯性的作用。同时,考虑到控制系统的特点以及储能系统和可再生能源的局限性,建立了虚拟惯量的设计框架。最后,几个新的自适应惯性控制策略进行了审查,并建议未来的研究的一些方面。

英文摘要:

With the increasing impact of low inertia due to the high penetration of distributed generation, virtual synchronous generator (VSG) technology has been proposed to improve the stability of the inverter-interfaced distributed generator by providing "virtual inertia". This paper presents a recent review of virtual inertia control covering significance, features, design principles, and state-of-art inertia strategies from both physical and mathematical perspectives to facilitate the wide application of the VSG. The definition and source of virtual inertia are given to help researchers to establish the concept of "virtual inertia". Then, this paper covers influencing mechanism studies of virtual inertia to reveal its functions. Also, a design framework of the virtual inertia is established by considering both the characteristics of the control system and the limitation of energy storage systems and renewable energy resources. Finally, several novel adaptive inertia control strategies are reviewed, and some aspects of potential future research are recommended.
