基于能源互联网的能量传输建模及线路布配

Modeling the Energy Transmission based on the Energy Internet and Lines Connection

本文利用供、用能端相互联系、相互补充的能源互联网供能模式缓解资源分布和用能需求的不均衡,目的是降低全国范围的能耗率及用能成本。首先通过能量密度法计算出各地区供用能分布对应的能量节点坐标,在此基础上建立各节点间能量传输模型;然后提出主汇点星型连接、主干线路垂直法两种几何法应用于能源互联网的传输线路优化,并分析其在能量传输模型优化中的优劣;最后采用综合连接法对西北地区枢纽节点间能量传输的线路连接进行设计,对比三种方法,得出该区域的最佳输配方案,解决其资源分布与用电负荷不相匹配问题。

With the interconnected and complementary energy supply mode of the energy internet instrumental in alleviating the imbalance of energy allocation and energy demand, this paper aims to reduce the energy consumption rate and cost. Firstly, it calculated the coordinates of energy supply and consumption hubs by the energy density method, then modeling the energy transmission between energy hubs. Then it raised two geometric methods, star connection of main aggregation point and vertical connection of trunk lines, which can be used to optimize the energy internet transmission lines, and it analyzed the advantages and disadvantages in the optimization of energy transmission model. Finally, it proposed a method with those two methods, it to design the connection of energy transmission between the hubs in Northwest China. By comparing these three methods, obtained the best transmission scheme and solved the problem of the imbalance between energy allocation andenergy demand.
