新型配电系统形态演进探索:渗流理论视角
Exploration of the Evolution of New Distribution System Forms:A Percolation Theory Perspective
摘要
Abstract
The high penetration of distributed energy resources is accelerating the topology evolution of distribution systems,necessitating research on cost-effective dynamic evolution pathways.This paper introduces and develops percolation theory to address"where to start"and"how to evolve"in distribution system topology evolution.First,this paper establishes a heterogeneous percolation model coupled with electrical constraints to achieve dynamic coupling between topology configuration and power flow constraints.Then,by analyzing percolation thresholds and the electrical functional giant connected component,identification methods for structural and functional bottlenecks are proposed.On this basis,this paper develops a reverse percolation-guided evolution path optimization method to identify critical investment intervals that trigger performance transitions.Case studies on a Czech urban distribution network demonstrate that prioritizing functional bottleneck expansion effectively avoids performance degradation caused by blind investment.Results from the modified IEEE 37-node system show that the proposed method improves distributed generation hosting capacity by 11.36%compared to traditional approaches with the same number of added branches,validating the effectiveness of the proposed methodology.关键词
