摘　　要：虚拟同步发电机(VSG)技术近年来发展迅速,将逐渐成为未来新能源的发展方向,VSG技术的应用可能对系统原有稳定性问题造成影响或者引入新的稳定性问题。首先回顾了虚拟同步机主要技术路线并对VSG并网稳定性问题和分析方法进行了概述,然后从影响因素、防控措施两方面对已有的研究成果进行了综述,最后对已有研究存在的问题进行了梳理并对未来的发展方向进行了展望。The technology of virtual synchronous generator （VSG） is developing rapidly in recent years and gradually becomes a new development direction for new energy sources. The application of VSG technology may introduce new stability problems and affect stability characteristics of traditional power system. The stability issue and analysis methods of grid-connected VSGs is summarized based on the review of main technology roadmaps of VSG. Afterwards, current research findings are reviewed in terms of influencing factors and preventive measures. Problems of current research are summarized at last and development direction in the future is forecasted.
