Aiming at the problem that output voltage of the distributed generator（ DG） is affected by different impedance in microgrid electric transmission line

consistency algorithms and event-triggering control are introduced to the hierarchical control of the microgrid. The trigger condition is divided according to the output voltage deviation value of DG

and different voltage compensation modes are triggered by different voltage deviation levels. The consistency algorithm is optimized for the communication delay among different DGs. The effectiveness of the event trigger voltage compensation and the improved delay consistency algorithm is verified on the MATLAB/SIMULINK simulation platform.
