论文摘要
可再生能源的渗透增加导致同步发电机的逐步逐步逐步淘汰，这构成了电力系统的频率稳定性的主要来源。鉴于这些变化，在过去的几年中，一些电力系统开始表现出以双峰行为为特征的奇数分布。这会导致涡轮调节器的磨损增加，并且通常以退化的频率性能。这是引起电网运算符的关注的原因，网格操作员对了解构成频率分布的因素变得越来越感兴趣。本文探讨了不需要的频率分布的根本原因。详细介绍了某些主要聚合系统参数对频率分布的影响。本文还表明，所谓的合成惯性的实现会导致强大的单峰频率分布。
The increasing penetration of renewable energy sources has been leading to the progressive phase-out of synchronous generators, which constitute the main source of frequency stability for electric power systems. In the light of these changes, over the past years, some power systems started to exhibit an odd frequency distribution characterised by a bimodal behavior. This results in increased wear and tear of turbine governors and, in general, in degraded frequency performances. This is a cause of concern for grid operators, which have become increasingly interested in understanding the factors shaping frequency distribution. This paper explores the root causes of unwanted frequency distributions. The influence of some main aggregate system parameters on frequency distribution is detailed. The paper also shows that the implementation of the so-called synthetic inertia can lead to a robust unimodal frequency distribution.
