摘要

传统的控制策略在面对高功率充电需求和电网电压波动时难以适应实际需求。为此

提出基于交错并联虚拟直流电机（VDCM）控制策略以期提高新能源充电站稳定运行能力。将交错并联DC/DC应用到充电站拓扑结构中

有效减小电动车充电站输出电流纹波

提高充电站的电能质量和稳定性;同时引入VDCM控制策略

为新能源充电站输出提供稳定可靠的惯量、阻尼支撑

实现对新能源充电站输出电压和电流的精确控制。基于小信号模型分析了转动惯量及阻尼系数对充电系统稳定性的影响情况

并通过Matlab/Simulink搭建的仿真模型分别选用电动汽车和电动重卡两种车型接入/断开充电站进行仿真验证。

Abstract

Conventional control strategies are difficult to adapt to the actual demand changes when encountering high power charging demand and grid voltage fluctuations. To this end

the interleaved parallel virtual DC machine control strategy is used to improve the stable operation capability of new energy charging station in this paper. The interleaved parallel DC/DC converter is used in the charging station system

which can effectively reduce the electric vehicle charging station output current ripple and improve the power quality and stability of the charging station; Meanwhile

the DC/DC converter using VDCM control strategy can provide stable and reliable inertia and damping support for the output of the new energy charging station

which realizes the precise control of the output voltage and current of the new energy charging station. Finally

the small signal model is used to analyses the effect of rotational inertia and damping coefficients on the stability of the charging system. And the physical simulation model of the new energy charging system is constructed based on the Matlab/Simulink software

which was used to simulate and validate the two models of electric cars and electric heavy trucks to connect/disconnect the charging station.
