This paper presents an impact analysis of communications in frequency and active power control in hierarchic multi-microgrid structures. Since communications can potentially introduce significant difficulties in the operation of electric power systems, particularly in the case of islanded multi-microgrids, an assessment is performed considering delays and losses that control information is likely to experience when traversing the communication infrastructure. Results show that the impact of communication difficulties under most simulated scenarios is reduced, whereas in more demanding scenarios the control structure can have a significant role in minimizing the impact of communication failures.
