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.
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.
