摘要:
      虚拟同步发电机(VSG)技术可使新能源发电设备具有与同步机类似的频率和电压支撑能力,因此得到广泛关注。目前相关研究主要关注VSG本体模型及控制策略,同时工程应用场景主要为微电网。从大容量并网新能源VSG示范工程建设中遇到的难点出发,结合目前新能源发展中遇到的相关技术问题,将VSG并网后在复杂电网工况下的安全高效运行概括为VSG的并网适应性问题,包括并网稳定、故障穿越和风电VSG转子惯量支撑。对于并网适应性问题,分别总结和梳理了已有研究成果和局限性,针对性地介绍了相关研究进展,并对未来的研究方向进行了展望。
Abstract:
      Virtual synchronous generator(VSG)technology is widely concerned because it can help renewable power generation equipment equipped with frequency and voltage support capabilities similar to synchronous machines. The models and control strategies of VSG are now focused on and VSG is mainly applied in the microgrid. Started with the difficulties encountered in the demonstration project of the large-capacity grid-connected renewable VSG, combined with the relevant technical problems of renewable energy development, the safe and efficient operation problems of the grid-connected VSG in the complex conditions are summarized as the grid-connected adaptability of VSG, including grid-connected stability, fault ride-through, and frequency support based on rotor inertia of wind power VSG. For various aspects of grid-connected adaptability problems, the existing research results and limitations are summarized, relevant research progress is specially introduced, and the future research directions are prospected.
