摘要

为解决绿色拖轮在作业中引起的电力系统直流母线电压波动过大以及柴油发电机组和储能系统短时过载等问题,提出将带有电压补偿的下垂控制与虚拟直流发电机控制融入混合储能系统。先进行控制策略的理论分析,再基于Matlab/Simulink搭建混合储能系统,仿真验证控制策略可行性;最后将此控制策略融入绿色拖轮电力系统进行仿真实验。结果表明,融入混合储能控制策略后绿色拖轮柴油发电机组可以在除停泊工况外全工况下持续输出经济功率,直流母线电压稳态时稳定输出额定电压1000 V,暂态过程中电压波动≤1.5%,所提控制策略大大提高了绿色拖轮电力系统安全性和稳定性。

Abstract

To solve the issues posed by excessive DC bus voltage fluctuations in power systems and short-term overloads in diesel generator sets and energy storage systems, a control strategy that integrates droop control with voltage compensation and virtual DC generator control into hybrid energy storage systems is proposed for green tugboat operations. Firstly, a theoretical analysis of the control strategy is presented. Subsequently, a hybrid energy storage system model is constructed in Matlab/Simulink to simulate and verify the feasibility of the control strategy. Finally, the control strategy is integrated into the green tugboat power system to conduct simulation experiments. The results demonstrate that the green tugboat's diesel generator set, which incorporates the hybrid energy storage control strategy, is capable of continuously outputting economical power under all operating conditions except the mooring condition. Furthermore, the DC bus voltage reains at the rated voltage of 1000 V in steady state. Additionally, the voltage fluctuation in the transient process is less than 1.5%. The proposed control strategy has been shown to significantly enhance the safety and stability of the green tugboat power system.
