Optimal Design of Power Supply Scheme for Sharing Resources in Urban Rail Interchange Stations
摘要
Abstract
In the context of power supply resource sharing between different lines through interchange stations,optimizing the power supply system design can help reduce active power losses in the network.By considering the constraints of multi-operation scenarios,a novel optimal design method for a power supply scheme for sharing resources in urban rail interchange stations based on a triple-checking algorithm was proposed.A topological model for centralized power supply systems for urban rail and a mathematical model for resource sharing in interchange stations were established.A multi-branch tree topology search was employed to generate a candidate solution set,which was then optimized using the triple-checking algorithm to identify the optimal power supply scheme with the lowest active power loss in the network.An analysis was performed using the actual power supply system of five lines as an example.The results show that compared to the traditional main substation-based power supply scheme for sharing resources,the proposed power supply scheme for sharing resources in urban rail interchange stations reduces the initial construction costs of the overall power supply system and reduces annual operational network losses by 2 296.580 MW·h.关键词
