中文摘要

电动汽车电池测试系统(PABTS)的并联运行构成了直流微电网。由于直流母线电容惯性较低,系统在充放电切换时电压波动显著。本文提出一种分数阶虚拟惯量控制方法,通过优化惯量响应特性,有效增强了直流微电网的电压调节能力,提升了系统的动态稳定性和抗干扰性能。

English Abstract

Electric vehicle (EV) has been widely used in our life, one of the key technologies is the batteries, power accumulator battery test system (PABTS), which is initiated for evaluating the performance of the EV batteries, has been used in many battery-manufacture companies. The parallel operation of the PABTS forms a dc-microgrid, owing to the low inertia of the dc-link capacitance, the charging and...
