混合储能系统增强型自抗扰协调控制

COORDINATED CONTROL OF HYBRID ENERGY STORAGE BASED ON ENHANCED ACTIVE DISTURBANCE REJECTION CONTROL

  • 摘要: 针对复杂扰动下微电网难以实现理想动态问题,依据分频框架和线性自抗扰控制(LADRC)理论,提出一种混合储能增强型自抗扰协调控制策略。该方案在外环中引入级联型线性扩张状态观测器(LESO)以输出理想的波动平抑指令,提高抗扰性。同时,在内环的自抗扰控制律中引入参考微分前馈以优化对外环输出指令的跟踪能力,进而改善动态性能。基于理论分析,从扰动观测精度、参考跟踪误差、扰动衰减等方面分析增强型自抗扰协调控制的优越性,并为参数整定提供指导思想。最后,在半实物仿真平台上对所提策略的性能进行对比测试,验证其可行性和有效性。

     

    Abstract: It is difficult to realize the ideal dynamic of microgrid under complex disturbance. Based on the frequency division framework and linear active disturbance rejection(LADRC) theory, a hybrid energy storage enhanced active disturbance rejection coordinated control strategy is proposed in this paper. In this scheme, a cascade linear extended state observer(LESO) is introduced into the outer loop to output an ideal wave suppression instruction and improve the immunity. At the same time, the reference differential feedforward is introduced into the auto-disturbance rejection control law of the inner loop to optimize the tracking ability of the output instructions of the outer loop and improve the dynamic performance. Based on the theoretical analysis, the advantages of the enhanced active disturbance rejection coordination control are analyzed from the aspects of disturbance observation accuracy, reference tracking error and disturbance attenuation, and the guiding ideology is provided for parameter tuning. Finally, the performance of the proposed strategy is tested on the semi-physical simulation platform to verify its feasibility and effectiveness.
