The distributed hierarchical control method is preferred in microgrids to reduce the communication issues such as shortening the communication distance, decreasing the communication traffic and minimizing the failures. However, failure to detect changes in loads due to communication problems can lead to disturb the proportional current sharing and voltage stability of the microgrid. Therefore, this paper proposes an estimation algorithm to maintain both the voltage stability and the proportional current sharing between the sources in case of communication failures between the controllers. The algorithm is created using the weighted moving average method and estimates the data that should come from the neighbors during any failure. In order to test the performance of the algorithm, its simulation is performed in Matlab/Simulink and it is observed that the proposed algorithm has better results than conventional ones like zero order hold.
