  The Role of Power Electronics in Future Low Inertia Power Systems

 

  摘要:

  Inertia plays an essential role in maintaining the frequency stability of power systems. Nevertheless, the increase of power electronics-based renewable generation can dramatically reduce the inertia levels of modern power systems. This issue has already challenged the control and stability of small-scale power systems. It will soon be faced by larger power systems as the trend of renewable integration continues. In this seminar, I will give a review of emerging power electronics-based inertia enhancement techniques. Among these techniques, inertia emulation by wind turbines has successfully demonstrated its effectiveness and will receive widespread adoptions. In addition, virtual inertia emulated by the DC-link capacitors of power converters has great potentials due to its low cost. The same concept can also be applied to ultracapacitors. Moreover, batteries such as those used for vehicle-to-grid can serve as an alternative inertia supplier. In future power systems where most of the generators and loads are connected via power electronics, virtual synchronous machines will become the main inertia provider. In general, it is concluded that advances in semiconductors and control promise to make power electronics an enabling technology for inertia control in future power systems.

  电力系统惯性在维持电力系统的频率稳定性方面起着至关重要的作用。然而,基于电力电子的可再生能源发电的增加会大幅度降低现代电力系统的惯性水平。相关问题已经对小型电力系统的控制和稳定性提出了挑战。随着近些年可再生能源一体化的发展,大型电力系统将面临类似的问题。本次讲座将对新兴的基于电力电子的惯性增强技术进行介绍和回顾。其中,风力电机惯性仿真技术已成功证明其有效性并将得到广泛采用,而由直流侧电容器仿真的虚拟惯性仿真技术由于其低成本而具有很大的发展潜力。类似的概念也可以应用于超级电容器的研究。此外,诸如用于电动汽车入网技术(V2G)的动力电池亦可以为电网提供惯性。由于未来大多数发电设备和负载将通过电力电子设备并网,讲座最后将介绍虚拟同步电机技术如何为电网提供惯性支持。
