随着世界范围内可再生能源(RESS)使用的增加，人们越来越关注可再生能源对电力系统运行和控制的影响。概述了与可再生能源机组并入电力系统有关的频率调节方面的关键问题和新挑战。在简要介绍了存在的挑战和最新发展之后，还介绍了各种可再生能源(如风能和太阳能组件)产生的功率波动对系统频率性能的影响。介绍了一种更新的LFC模型，并分析了电力系统在RESS存在时的频率响应及相关问题。强调了修订频率性能标准的必要性。最后，在标准39节点和24节点测试系统上进行了非线性时域仿真，仿真结果与解析预测结果吻合较好。
As the use of renewable energy sources (RESs) increases worldwide, there is a rising interest on their impacts on power system operation and control. An overview of the key issues and new challenges on frequency regulation concerning the integration of renewable energy units into the power systems is presented. Following a brief survey on the existing challenges and recent developments, the impact of power fluctuation produced by variable renewable sources (such as wind and solar units) on system frequency performance is also presented. An updated LFC model is introduced, and power system frequency response in the presence of RESs and associated issues is analysed. The need for the revising of frequency performance standards is emphasised. Finally, non-linear time-domain simulations on the standard 39-bus and 24-bus test systems show that the simulated results agree with those predicted analytically.
