关于伊比利亚系统中由于高度可更新集成引起的惯性减小的频率稳定性特性的评估

Assessment of frequency stability behaviour regarding inertia reduction due to high renewable integration in the Iberian system

Francisco de Sousa Fernandes, Joao Pecas Lopes

摘要:

基于电子转换器的可再生能源的逐步集成将导致系统同步惯性的降低,这可能危及系统频率稳定性行为,特别是在隔离或互连不良的系统的情况下,例如伊比利亚半岛系统的情况。这项工作的重点是研究的影响,同步惯性减少可以对伊比利亚系统的频率稳定性不同的关键操作场景和干扰。为此,首先使用Matlab Simulink图形编程环境开发了与中欧网络互连的伊比利亚系统的等效动态模型。该模型的参数识别使用参数估计方法,探讨了记录的行为的频率后,在西班牙的一个核机组停运。随后使用该模型对2020年至2040年间不同的发电中断和多种运行场景进行了模拟。

英文摘要:

The progressive integration of electronic converter based Renewable Energy Sources will lead to a reduction of the system synchronous inertia that can endanger the system frequency stability behavior, especially in the case of isolated or poorly interconnected systems, such as the case of Iberian Peninsula system. This work focuses on the study of the impact that the synchronous inertia reduction can have on the Iberian system frequency stability for different critical operation scenarios and disturbances. For this purpose, an equivalent dynamic model of the Iberian system interconnected with the central European network was first developed using the Matlab Simulink graphical programming environment. The parameters of this model are identified using a parameter estimation approach that explores the recorded behavior of the frequency following an outage of a nuclear unit in Spain. This model was used afterwards to perform simulations for different generation outages and multiple operation scenarios between 2020 and 2040.
