On design of power sharing for VSC‐based islanded AC microgrids: An adaptive MIMO controller equipped with a predictor

open access: yesIET Generation, Transmission & Distribution, 2023
In an AC microgrid, the active/reactive power is usually shared among its distributed generators (DGs) based on the frequency‐active power (F−P) droop and the voltage‐reactive power (V−Q) droop.
