高速公路双侧服务区充电多源能流协同调度OA
Coordinated scheduling of multi-source energy flows for charging in dual-sided expressway service areas
针对高速公路双侧服务区充电负荷时空异质性导致的能量供需时空失配问题,提出基于直流互联技术的双侧服务区多源能流协同调度方法.首先,基于京昆高速韩村河服务区实际交通流、充电负荷及设备配置数据,分析车流量与充电需求的时空分布及耦合特征;然后,构建双侧服务区间双向能量互济通道,在日周期尺度上建立小时级优化模型,以碳排放最小化、经济收益最大化及电网波动量最小化为优化目标,并利用Gurobi求解器求解;最后,设置独立运行、光储充自洽和光-储-直-充三类调度方案开展对比仿真,并针对时间特征和天气条件进行敏感性分析.研究结果表明:车流量与充电需求在日周期尺度上存在显著同步波动关系,在假期及其他高出行强度场景下双侧服务区负荷空间差异更加明显;相较于独立运行方案和光储充自洽方案,光-储-直-充方案综合性能最优,日碳排放量分别降低71.2%和41.8%,经济收益分别提升17.1%和7.6%,电网功率波动量分别减少94.6%和66.7%,综合经济成本分别降低23.4%和9.0%;本方案在不同充电负荷时序分布和光伏出力条件下均表现出较强的适应性,在节假日出京高峰日、进京高峰日和周日等负荷空间分布差异大的典型场景中表现最佳,跨区互济能量分别达到438.5 kWh、236.9 kWh和166.3 kWh.研究结果可为高速公路双侧服务区光储充一体化系统的运行调度与低碳优化提供参考.
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.
