Abstract:In order to provide support for related research such as the vulnerability analysis of regional power networks, and the corresponding protection measures taken for power networks in different regional, considering the regional characteristics of the power system, and considering factors such as power capacity and spatial location of power facilities, distribution relationship of power facility density and density of regional population, this paper proposes a method of constructing a power spaced network model based on a complex network, which is called MProposed method, it can provide corresponding support for the formulation and implementation of regionally targeted protection measures. Taking the power system of a city in central China as the object, the paper constructs local and global networks by using the MProposed method, compares the system structure with the existing methods which include the method based on actual data, the method based on random generation and their improved algorithms by simulation analysis, finally, the results verify the effectiveness and regional adaptability of the MProposed method.
