6 FAQs about [Microgrid consistency secondary control]

Does communication delay affect AC microgrid control performance?

In this paper, distributed secondary control of AC microgrid (MG) is studied and the influence of communication delay on its control performance is analyzed and verified. Firstly, a secondary control strategy for the MG is designed to achieve frequency recovery and proportional active power dispatch.
