A novel control scheme is presented to eliminate the negative effects of communication disturbances, which introduces active disturbance rejection control (ADRC) in the control strategy design to achieve the objectives of the restoration of the bus voltage and the sharing of the power even in the presence of disturbances and delays in communication. Simultaneously, its dynamic disturbance decoupling feature is used to realise the decoupling between power and voltage, so that the proposed controller only exchanges power information with its neighbours, reducing the communication burden and simplifying control structure. The control performance of the strategy is verified by employing steady-state analysis. The impact of controller parameters is studied by establishing a small signal model. Finally, both simulation cases and experimental tests prove the feasibility of this scheme.

为了消除通信干扰的负面影响，提出了一种新颖的控制方案，该方案在控制策略设计中引入了自抗扰控制（ADRC），以达到即使在存在通信干扰的情况下也能恢复母线电压和共享功率的目的沟通的干扰和延迟。同时，利用其动态扰动解耦特性实现功率和电压之间的解耦，使得所提出的控制器仅与邻居交换功率信息，减少了通信负担并简化了控制结构。通过稳态分析验证了该策略的控制性能。通过建立小信号模型来研究控制器参数的影响。最后通过仿真案例和实验测试证明了该方案的可行性。
