用复杂网络理论分析电网及大停电事故

Analysis on Power Grids and Blackouts with Complex Network Theory

随着全球经济的迅速发展,电网的规模也在不断扩大,电网互联成为电力系统发展的必然趋势。但是由于近年来世界范围内大停电事故频频发生,带来了巨大损失,因此,引起了科学界对电网的研究热潮。用复杂网络理论分析了电网的拓扑结构和特性,说明其具有小世界和无标度特性。其次分析说明了研究电网的几个模型和各自的不足之处,这有利于科学家提出更好的模型来降低大停电事故带来的损失。

With the rapid development of the global economy, the power grid size. is also growing,power grid becomes the inevitable trend of the power system development. But recently, successive power blackouts of large scale occurred in the world,result in a great loss, which attracts researchers attention to the reliability of power grid. Firstly,analyzes the topology and property of the power grid, explains it has the small-world and the freescale. Secondly,analyzes and explains the model and the shortage of the power grids. It is advantageous to put forward the better model in order to lower the loss of the blackouts.
