Research on the Optimal Wiring Method of Distribution Network Lines Adapting to Multi-Level Dynamic Networking of Microgrids

With the deepening of power system reform, most existing distribution network planning methods struggle to adapt to the increasingly large network scale and complex wiring patterns under the current multi-microgrid and multi-level grid system. At the same time, with the progress of the times, people's requirements for distribution networks are also increasing. Therefore, issues such as the fragile structure of the distribution network and the convoluted and intersecting power supply lines are becoming increasingly prominent, posing risks to social and economic development and affecting the construction and operation maintenance of distribution networks. This paper studies the optimal selection of wiring methods for distribution networks that adapt to dynamic networking of multi-level microgrids. It analyzes the impact of different networking scenarios on distribution networks, focusing on the wiring methods and line capacities of distribution networks, and proposes relevant optimization methods. The aim is to address the existing problems in current distribution network planning and to propose a planning index system for distribution networks that adapts to flexible networking of hybrid energy microgrids. This paper will provide reference for the planning and construction of microgrids for the GS power grid.
