由于分布式发电的部署，未来电网将表现出惯性减小，从而导致更高的动态性和降低的频率稳定性。这在微电网 (MG) 中尤其如此。从这个意义上说，虚拟同步发电机（VSG）概念被提出作为一种有前途的解决方案。在本文中，进一步探讨了这一概念的好处，研究了在有关 MG 操作的不同情况的模拟下频率稳定性的改进。这里，进行分析，着眼于控制参数对频率变化率和平均频率偏差的影响。 VSG 概念显示出降低这两个参数以提高频率稳定性的巨大潜力。
Due to the deployment of distributed generation, future grids will show reduced inertia resulting in higher dynamics and reduced frequency stability. This is especially true in microgrids (MGs). In this sense, the virtual synchronous generator (VSG) concept has been proposed as a promising solution. In this paper, the benefits of this concept are further explored studying the frequency stability improvement under simulation of different cases regarding the MG operation. Here, the analysis is carried out looking at the impact of the control parameters on the rate-of-change-of-frequency and on the average frequency deviation. The VSG concept shows a great potential to reduce both parameters improving the frequency stability.
