Abstract：Considering the limited communication resources in the state monitoring process of renewable energy mi-crogrid system,a distributed blocking moving horizon estimation algorithm based on Round-Robin protocol is proposed.Building upon distributed moving horizon estimation,the Round-Robin protocol is introduced to reduce the communication burden of the sensor network.Under this protocol,each sensor node transmits its measurement component successively and periodically,avoiding data congestion and fully utilizing the limited bandwidth resources.Moreover,the disturbance sequence in the estimation window is designed using the block concept,which reduces the number of optimization variables and the amount of online computation.By analyzing the feasibility and convergence of the algorithm under the maximum block length,the sufficient conditions are established to guarantee the existence of an equivalent solution to the optimization problem of the algorithm,and the results are extended to the case of arbitrary block of the disturbance sequence.Simulation results show that the proposed algorithm can estimate the states of renewable energy microgrid system effectively.
