6 FAQs about [Microgrid frequency requirements]

How to control the frequency of a microgrid?

In (Doost Mohammadi et al. 2014), the authors presented an approach to divide the MG into virtual areas and control the frequency of the microgrid by using the tie-line error which is called Virtual Area Control Error (VACE) instead of just using the frequency deviation error (Fig. 9.16).
