考虑不确定性单峰-偏度信息的输配系统分布式分布鲁棒优化
Distributed Distributionally Robust Optimization of Integrated Transmission and Distribution System Considering Unimodality-skewness Information About Uncertainty
摘要
Abstract
In the context of carbon peaking and carbon neutrality goals,the coupling relationship between transmission and distribution networks is gradually strengthened,necessitating coordinated scheduling between transmission and dis-tribution systems.In this paper,a distributed distributionally robust optimization scheduling method for transmission and distribution systems considering the unimodality-skewness information about renewable energy uncertainty is pro-posed,which aims to improve the economic efficiency of scheduling results and address the packet loss issues under re-al communication conditions.First,to enhance the economic efficiency of scheduling results,a coordinated scheduling model for transmission and distribution systems based on the fuzzy set of unimodality,skewness and second-order mo-ment information is constructed with the consideration of the unimodality-skewness information about renewable energy uncertainty.Second,since the distributionally robust scheduling model is complex and difficult to solve directly,the duality theory is applied to transform the objective function and joint chance constraints into a deterministic reformulat-ed model.Third,to address the possible packet loss issues under real communication conditions,a relaxed alternating direction method of multipliers distributed algorithm considering communication packet loss is put forward based on the Peaceman-Rachford splitting theory and a binary probability distribution.Finally,simulation results demonstrate that the proposed method can improve the economic efficiency of scheduling results and achieve distributed coordinated scheduling in an environment with packet loss.关键词
