Abstract

The promotion of wind power generation can effectively optimise China's energy structure and promote the sustainable development of economy and society. However, the application and promotion of wind power will bring a new problem, that is, it increases the complexity of power system structure and poses a certain hidden danger to the security of power grid. Therefore, Kuramoto model is used to analyse the transient stability of power system, and a comprehensive evaluation system of power system stability is constructed from the two directions of static security and dynamic security. Finally, based on grey correlation analysis, a comprehensive evaluation model (GRA) of power system stability is constructed. The results show that the accuracy of the evaluation model reaches 97.5%. Therefore, the evaluation model can evaluate the stability of power system efficiently and accurately, and avoid large-scale blackouts caused by power system collapse.

基于灰色关联支持的电力系统稳定性评价研究

推广风力发电可以有效地优化中国的能源结构，促进经济社会的可持续发展。然而，风电的应用和推广将带来一个新的问题，即增加了电力系统结构的复杂性，并对电网的安全构成一定的隐患。因此，采用Kuramoto模型对电力系统暂态稳定性进行分析，从静态安全与动态安全两个方向构建电力系统稳定性综合评价体系。最后，在灰色关联分析的基础上，建立了电力系统稳定性综合评价模型。结果表明，该评价模型的准确率达到97.5%。因此，该评估模型可以高效、准确地评估电力系统的稳定性，避免因电力系统崩溃而造成大规模停电。

期刊介绍： The explosive growth of wide-area cellular systems and local area wireless networks which promise to make integrated networks a reality, and the development of "wearable" computers and the emergence of "pervasive" computing paradigm, are just the beginning of "The Wireless and Mobile Revolution". The realisation of wireless connectivity is bringing fundamental changes to telecommunications and computing and profoundly affects the way we compute, communicate, and interact. It provides fully distributed and ubiquitous mobile computing and communications, thus bringing an end to the tyranny of geography.
