摘要:

近年来,储能式有轨电车得到大力发展,其中结合地面充电装置与储能技术的新型有轨电车供电制式是目前的研究热点。本文基于现有某线路有轨电车已投入使用的运行模式展开研究,结合地面充电装置与储能技术,构成车(锂电池和超级电容)+地(地面充电桩)的动力系统,在保证有轨电车运行和安全性的前提下,建立地车地一体化动力系统经济型模型,并采用粒子群优化算法求解得到了经济性最优的容量配置方案。通过对比分析,本文提出的新型容量配置方案与现有的纯超级电容“站站充”模式相比,在日均成本上降低了9.8%,综合总成本节省了1064万元,对地面充电站充电功率需求降低了66.7%。

Abstract:

In recent years, the development of energy storage trams has attracted considerable attention. Our current research focuses on a new type of tram power supply system that combines ground charging devices and energy storage technology. Based on the existing operating mode of a tram on a certain line, this study examines the combination of ground-charging devices and energy storage technology to form a vehicle (with a Li battery and a super capacitor) and a ground (ground charging pile) power system. Under the premise of tram operation and safety, an economic model of the integrated power system of ground, vehicle, and ground is established, and a particle swarm optimization (PSO) algorithm is used to obtain the most economical capacity allocation plan. Through a comparative analysis and compared with the existing pure supercapacitor "station charging" mode, the new capacity configuration scheme proposed in this study would reduce the average daily cost by 9.8% and save 10.64 million yuan in the overall cost. The charging power requirements would be reduced by 66.7%.

Key words: energy storage trams, super capacitors, lithium batteries, ground charging stations, capacity configuration
