| 摘要: |
| 针对孤岛直流微电网，提出一种数据驱动的无模型二次控制策略。利用直流微电网系统输入、输出的过程数据以及偏格式动态线性化方法建立系统的数据模型。通过设计新型的无模型二次功率和电压控制器，分布式电源按其容量成比例地输出功率，同时使用最大电压补偿的方法恢复系统母线电压。通过数学分析严格证明该直流微电网系统在不同运行条件下是闭环控制稳定的。最后，利用MATLAB/Simulink仿真和RTDS实验平台，验证了所提控制策略的有效性。 |

| Abstract: |
| As for the islanded DC microgrid, a data-driven model-free secondary control strategy is proposed. The data model of system is established using the input and output process data of DC microgrid system and the partial format dynamic linearization method. Through designing the novel model-free secondary power and voltage controller, the proportional power allocation of distributed generation by its capacity can be achieved and the maximum voltage compensation method is used to restore the bus voltage of system. Through mathematical analysis, it is strictly proved that the DC microgrid system is stable in closed-loop control under different operation conditions. Finally, the effectiveness of the proposed control strategy is verified by MATLAB/Simulink simulation and RTDS experiment platform. |
