Research on the Evolution of Distribution Network Form under the Background of New Power System

With the promotion of the dual carbon goal and the construction of a new power system, the development of the distribution network is facing higher requirements. Large-scale access to new elements of source, load and storage, such as distributed power generation, multiple loads, and energy storage, will accelerate the upgrading of the functional form of the distribution network. In this paper, a four-dimensional D-M-S-T analysis framework is proposed to analyze the morphological evolution of distribution network, which is divided into timeline, morphological axis, scene axis and driver axis. The timeline divides the future into short, medium and long-term periods, namely 2025, 2030 and 2060, according to the years of the city's overall plan. The scenario axis is divided into urban, rural, and industrial parks according to the economic and social development and power grid development differences in different regions. The morphological axis is divided into grid state, information state and commercial state according to the functions of each part of the power grid. The driver axis considers the impact of the three-sided changes of source, load and storage on the power grid. This paper analyzes the evolution paths of various forms of power grids in the short, medium and long term driven by different drivers in different scenarios, which solves the problem of obvious differentiation in the development of distribution networks and unclear evolution of forms.
