Abstract: The development of the regional energy network is an essential part in the construction of new-type towns. It is of great significance to analyze the evolution law and morphological characteristics of the regional energy network for guiding its planning and operation. This paper proposes an evolving model of the regional energy network considering town growth characteristics. Firstly, the growth characteristics of spatial load are summarized according to the town growth characteristics, and the growth process of the town load is simulated based on the random geometric graph model of the complex network theory. Then, with the objective of minimizing the investment and construction cost, the distribution of the energy stations and the integrated pipelines of the regional energy network is obtained, and the evolving process of the regional energy network is given. Furthermore, the spatial and topological characteristics of the evolution model are analyzed theoretically. The simulation results show that the evolved regional energy network conforms to the growth characteristics of the town and load, and its morphological characteristics are consistent with the theoretical analysis and similar to the actual power grid, which verifies the rationality of the proposed model.
