电力系统正在从以燃料为基础的发电向以电力电子为接口的可再生发电和输电过渡。这一转变挑战了从毫秒到季节的标准电力系统建模、分析和控制范例。本教程重点介绍毫秒到秒的时间尺度上的频率稳定性。我们首先回顾了电压型换流器(VSC)、典型的可再生能源发电和高压直流输电(HVDC)的电网跟踪(GFL)和电网形成(GFM)控制的基本结果。在这种情况下，运行新兴电力系统显然需要GFL和GFM控制功能。然而，在同一系统上组合GFL资源、GFM资源和遗留生成会导致高度复杂的动力学，这是稳定性分析的重大障碍。本教程的其余部分概述了通用GFM控制的最新发展，这些GFM控制弥补了GFL和GFM控制之间的差距，并提供了一种考虑发电、电力转换和电力传输的连贯控制和分析框架的途径。
Electrical power systems are transitioning from fuel-based generation to renewable generation and transmission interfaced by power electronics. This transition challenges standard power system modeling, analysis, and control paradigms across timescales from milliseconds to seasons. This tutorial focuses on frequency stability on timescales of milliseconds to seconds. We first review basic results for grid-following (GFL) and grid-forming (GFM) control of voltage source converters (VSCs), typical renewable generation, and high voltage direct current (HVdc) transmission. In this context, it becomes apparent that GFL and GFM control functions are needed to operate emerging power systems. However, combining GFL resources, GFM resources, and legacy generation on the same system results in highly complex dynamics that are a significant obstacle to stability analysis. The remainder of the tutorial provides an overview of recent developments in universal GFM controls that bridge the gap between GFL and GFM control and provide a pathway to a coherent control and analysis framework accounting for power generation, power conversion, and power transmission.
