轨道交通多源互补供电系统协同效果评价技术综述OA

The multi-source complementary power supply systems in rail transit involve numerous systems and diverse energy sources,with high coupling requirements among subsystems.Quantifying their synergy effect scientifically and rationally has important guiding significance for the full life cycle optimization of the systems.Based on the"source,grid,load,storage,and intelligence"architecture and combined with the characteristics of the rail transit industry,a three-dimensional comprehensive evaluation index system covering technology,economy,and environment was summarized and formed.For the weight allocation of indicators in the evaluation,the applicability of weighting methods was analyzed.The combination weighting based on game theory was used to resolve the conflict between subjective and objective weights,and an evaluation weight system was constructed.Commonly used comprehensive evaluation models were compared.The multi-criteria compromise solution ranking evaluation model embedded with an uncertainty processing mechanism could balance compromise solution optimization under multi-objective conflicts and fuzzy information processing and was more suitable for multi-dimensional evaluation requirements.This paper prospected the application value of synergy effect evaluation in scenarios such as system planning and design and equipment configuration,which can provide theoretical support and technical reference for the sustainable development of multi-source complementary power supply systems in rail transit.
