华北电力大学程鹏团队最新研究论文：基于电压偏差和SoC的电氢耦合系统多源协调控制策略

近日，华北电力大学(North China Electric Power University)程鹏团队以《基于电压偏差和SoC的电氢耦合系统多源协调控制策略》为题在《电机与控制应用》上发表最新研究论文，第一作者为赵艺徽，通信作者为程鹏。

针对公路直流微电网中“风光储氢”多态能源协调控制需求，提出一种基于母线电压偏差的多源协调控制策略。该控制策略以蓄电池作为直流母线电压的稳定核心，以电解槽和燃料电池作为辅助单元，平衡电网功率波动，实现公路直流微电网的稳定运行。同时，为避免储能因SOC异常而退出运行，提出一种考虑储能SOC的多源自适应下垂控制器，通过对蓄电池和氢能单元进行实时功率分配，使氢能单元主动响应SOC变化，以缓解蓄电池在SOC管理过程中所造成的不平衡功率，同时使SOC向设定值趋近。

本文主体内容包括以下几个部分：首先，介绍了公路直流微电网的系统组成，并对系统中电动汽车的时间特性和充电方式特性进行了分析，然后设计了基于直流母线电压偏差信号的多源协调控制策略，同时，根据传统下垂控制的缺陷提出了基于储能SOC的多源自适应下垂控制器，并对其进行了机理分析，最后通过Simulink仿真平台验证了所提控制策略的有效性。

本文所提策略不仅能够缓解多态能源系统输电阻塞，降低变流器控制策略切换次数，且能提高储能单元使用寿命和可再生能源利用率，具有较高的工程应用价值。

Multi-Source Coordinated Control Strategy Based on Voltage Bias and SOC for Electro-Hydrogen Coupling System

A multi-source coordinated control strategy based on bus voltage deviation is proposed to meet the requirements of coordinated control of multi-morphic energy sources "wind, light, storage and hydrogen" in highway DC microgrids. The control strategy takes the storage battery as the core of DC bus voltage stabilization, and the electrolyzer and fuel cell as auxiliary units to balance the power fluctuation of the grid and realize the stable operation of the highway DC microgrid. Meanwhile, in order to prevent the energy storage unit from shutting down due to SOC abnormality, a multi-source adaptive droop controller considering the storage SOC is proposed, which enables the hydrogen unit to actively respond to the SOC change by real time power allocation between the battery and the hydrogen unit to alleviate the unbalanced power caused by the battery in the process of SOC management, and at the same time converge the SOC to the set value.
The main content of this paper includes the following parts: first, the system composition of highway DC microgrid is introduced, and the time characteristics and charging mode characteristics of electric vehicles in the system are analyzed, and then a multi-source coordinated control strategy is designed based on the DC bus voltage deviation signals, and at the same time, a multi-source adaptive droop controller based on SOC is proposed based on the defects of the traditional droop control, and the mechanism of it is analyzed, and finally the effectiveness of the proposed control strategy is verified by Simulink simulation platform.
The strategy proposed in this paper can not only alleviate the transmission blockage of polymorphic power system and reduce the number of converter control strategy switching, but also improve the service life of energy storage unit and the utilization rate of renewable energy, which is of high value for engineering applications.
