摘要:
为了减少能耗和能源系统成本,考虑到高铁运行能源负荷与能源系统规划设计之间的相互影响,研究光伏接入条件下基于源-荷互动的的高铁网-源-储-车定容优化方法,提出一种基于节能操纵和列车运行图的列车群能源负荷评估方法,该方法同时考虑列车牵引和辅助用能需求,采用时空离散技术手段,揭示列车群能源负荷演化规律; 通过利用高铁线路周边的宜能空间,提出高铁沿线光伏发电潜力评估模型; 在此基础上,考虑网、源、储、车之间的能量转移关系,建立以经济效益最大化为目标的高铁光储定容优化模型。以京广(北京—广州)线某区间为例,通过对比4种不同场景的规划结果,验证提出模型方法的有效性。研究结果表明:在节能运行和光储接入场景下,高铁列车运行成本每年可以减少约445万元,能耗成本降低6.5%左右,同时每年可以减排CO219 072 t; 从能源负荷评估、光伏发电潜力评估和光储定容优化等方面,系统建立了高铁光储牵引供电系统定容优化方法,所提方法不仅有助于降低高铁用能成本,还具有较高的实用价值和推广意义。
Abstract:
To reduce energy consumption and system costs, an optimization method for the fixed capacity of high-speed rail network-source-storage-train systems under photovoltaic(PV)integration conditions was investigated, considering the interaction between energy load in high-speed rail operations and energy system planning. An energy load evaluation method for train groups based on energy-saving operations and train schedules was proposed, taking into account both traction and auxiliary energy demands. Spatiotemporal discretization techniques were employed to reveal the evolution patterns of energy loads in train groups. Additionally, a model was developed to assess the PV power generation potential along high-speed rail lines by utilizing the available energy space near the railway. A capacity optimization model aimed at maximizing economic benefits was established, considering energy transfer among the network, source, storage, and trains. A case study on a section of the Beijing-Guangzhou high-speed rail line was conducted to validate the effectiveness of the proposed model, comparing planning results under four different scenarios. The results show that under energy-saving operations and PV-storage integration, annual operational costs of high-speed rail can be reduced by approximately 4.45 million yuan, with a 6.5% reduction in energy consumption costs and a CO2 emission reduction of 19 072 tons per year. This research systematically establishes an optimization method for PV-based traction power systems, covering energy load evaluation, PV power generation potential assessment, and PV-storage capacity optimization. The proposed approach not only reduces energy costs in high-speed rail operations but also holds significant practical value and scalability for broader applications.2 tabs, 13 figs, 23 refs.
