The Evolution Model of Three-generation Power Systems and Characteristic Analysis

三代电网理论将电网发展历程可归纳为三个阶段——第一代小型电网、第二代大型互联电网和第三代智能电网。根据该理论文中分析了三代电网发展历程,从物理层面出发,归纳总结驱动和制约电网演化生长的主要因素,在此基础上提出一种电网演化生长模型,利用该模型成功复现了三代电网演化生长过程,初步奠定了三代电网理论的数学基础。进一步,在长时间尺度上对三代电网演化结果多项网络结构统计特性指标进行计算分析,分析结果从复杂网络层面验证了三代电网理论的正确性和前瞻性。

The power grid’s evolution is summarized as three generations, which are small-scale grid, large-scale interconnected power grid and smart grid respectively. Based on the theory of three-generation power systems, this paper analyzes the development history of three-generation power systems in the physical level at first. Then it summarizes the main driving and restricting factors of grid evolution. Furthermore, an evolution model of three-generation power systems is established, which can reproduce the evolutionary process of three-generation power systems successfully. It provides mathematical basis for the theory of three-generation power systems. Moreover, the statistical properties of the proposed model are analytically studied, and the results show that the new grid evolution model captures the essential features of real power grid.
