Power Oscillation Suppression of Multi-VSG Considering Non-Uniform Communication Delays
随着新能源渗透率的不断提高,电力系统中虚拟同步发电机(virtual synchronous generator,VSG)技术由于能提高系统频率稳定性,已成为新能源并网的关键技术.然而,多虚拟同步机系统会产生严重的功率振荡问题.针对这一问题,提出了一种分布式自适应参数抑制虚拟同步机功率振荡的方法.首先,将虚拟阻抗与频率变化率以及自适应惯量相结合,有效抑制了多VSG系统的功率振荡.其次,在传输线路通信延迟非均匀的情况下,提出了将集中控制和分布式控制…查看全部>>
With the rapid development of renewable energy sources,virtual synchronous generators (VSG) have garnered significant attention as a key technology for enhancing the stability of power systems. However,severe power-oscillation issues are inherent to multi-VSG systems. In this study,a control strategy was investigated for a multi-VSG parallel operation. A distributed adaptive parameter method is proposed to suppress power oscillations. First,by integrat…查看全部>>
