Abstract

This paper presents an energy management strategy for a battery-based stationary energy storage system (BESS) capable of supporting the operation of trolleybus power networks while adhering to the DC network's current and voltage requirements, as well as considering the limitation of the C-Rate, to avoid stress on the battery itself. This work also proposes the dimensioning of this BESS and the comparison of different battery capacities based on a Matlab/Simulink-based model able to simulate a one-day operation of the transit trolleybuses. This manuscript illustrates the effect of the proposed management and the chosen battery through comparisons of the voltage and current profiles along the line. The simulation results show an increase in the voltage level and a decrease in the line current along the catenary with the use of the BESS, indicating that the battery can be a solution to improve the operation of trolleybus systems, even though it is not usually used for this type of network.
支持无轨电车牵引动力系统的储能管理
本文提出了一种基于电池的固定式储能系统(BESS)的能量管理策略,该系统能够在满足直流电网的电流和电压要求的同时,支持无轨电车电网的运行,并考虑到C-Rate的限制,以避免对电池本身造成压力。这项工作还提出了该BESS的尺寸和基于Matlab/ simulink的模型的不同电池容量的比较,该模型能够模拟交通无轨电车的一天运行。本文通过对线路电压和电流分布的比较,说明了所提出的管理方法和所选电池的效果。仿真结果表明,在使用BESS后,沿接触网的电压水平升高,线路电流降低,这表明电池可以作为改善无轨电车系统运行的一种解决方案,即使它通常不用于这种类型的网络。
