Abstract: The distributed control strategy of the distribution network with distributed generation is expected to

solve the voltage control problem of the distribution network. However，distributed generation are loosely distributed in space，and communication problems such as communication delay and packet loss between nodes are inevitable.Traditional distributed control algorithms cannot well solve the voltage control challenges under this communication situation. Therefore，a distributed control strategy for distribution networks that comprehensively considers communication delay and packet loss was proposed. To address the issues of random delay and packet loss in abnormal communication processes，a sampling step optimization model was established with the goal of

minimizing the algorithm convergence time by introducing consistency gain coefficients and partially synchronized

iterative architectures in the consistency algorithm. The proposed algorithm achieves stable convergence of the

consistency algorithm and reduces the impact of channels with large communication delays on the iteration speed of the algorithm.
