高速公路双侧服务区充电多源能流协同调度
Coordinated scheduling of multi-source energy flows for charging in dual-sided expressway service areas
摘要
Abstract
To address the spatiotemporal mismatch between energy supply and demand caused by the spatiotemporal heterogeneity of charging loads in dual-sided expressway service areas,this study pro-poses a coordinated scheduling method for multi-source energy flows based on direct current intercon-nection technology.Utilizing actual traffic flow,charging load,and equipment configuration data from the Hancunhe Service Area on the Jingkun Expressway,this study first analyzes the spatiotemporal distribution of traffic flow and charging demand,as well as their coupling characteristics.Second,it constructs a bidirectional energy mutual-support channel between the dual-sided service areas and es-tablishes an hourly optimization model on a daily timescale.The model aims to minimize carbon emis-sions,maximize economic benefits,and minimize power grid fluctuations,and is solved using the Gu-robi solver.Finally,three scheduling schemes,independent operation,Photovoltaic-Storage-Charging(PSC)self-consistency,and Photovoltaic-Storage-Direct Current-charging(PSDC)integra-tion,are established for comparative simulation.Furthermore,a sensitivity analysis is conducted con-cerning temporal characteristics and weather conditions.The results demonstrate a significant synchro-nous fluctuation between traffic flow and charging demand on a daily timescale,with spatial load dis-crepancies between the dual-sided areas becoming notably more pronounced during holidays and other high-travel-intensity scenarios.Compared to the independent operation and PSC self-consistency schemes,the PSDC integration scheme achieves the best comprehensive performance.Specifically,daily carbon emissions are reduced by 71.2%and 41.8%,economic benefits are increased by 17.1%and 7.6%,grid power fluctuations are decreased by 94.6%and 66.7%,and comprehensive economic costs are lowered by 23.4%and 9.0%,respectively.Furthermore,this scheme exhibits strong adapt-ability under various temporal charging load distributions and photovoltaic output conditions.It per-forms optimally in typical scenarios characterized by significant spatial load discrepancies,such as peak outbound holiday travel days,peak inbound holiday travel days,and Sundays,where the cross-area mutual-support energy reaches 438.5 kWh,236.9 kWh,and 166.3 kWh,respectively.These findings provide a valuable reference for the operational scheduling and low-carbon optimization of integrated PSC systems in dual-sided expressway service areas.关键词
