摘要
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.
