小世界网络是复杂网络理论中的重要网络模型,而现实世界中的许多大型电力网络都具有小世界结构特征.本文基于复杂网络理论构建了小世界电网的生长演化模型,该模型能够考虑电网生长演化过程中发电厂和变电站建设的诸多要素,包括选址、定容以及接入电网方式等,分析并揭示电网演化过程中其网络拓扑结构特征.进一步,基于"网络结构决定网络功能"基本理念,根据直流潮流模型分析了小世界电网的潮流特性.研究表明处于长期稳态运行的小世界电网具有优越的潮流传输特性,特别对于负荷需求和运行方式的变化有较强的鲁棒性.

Small-world network is a significant network model in complex network theory. The small-world character is found in many huge power grids in the world. Evolutive model of small-world power grid is established based on Complex Network theory,which considered power plant and substation constructed in the process of power grid evolution,including where to build and ascertaining the capability of the power plant and substation,and how to link to system. Topological character is studied during the power grid evolution. Based on the basic idea that network structure decides network function,the power flow of the power grid is analyzed based on DC power flow model. The result shows that small-world power grid gains much more excellent power flow and robustness to the variety of power load demand and different operation modes of power grid.
