A distributed optimal control strategy based on finite time consistency is proposed in this paper, to improve the optimal regulation ability of AC/DC hybrid microgrid groups. The control strategy is divided into two steps: one is within a microgrid and the other is among microgrid groups.
Practically, microgrid controllers are designed to perform certain operation to serve multiple control objectives as listed down , . Bus voltage control and frequency control under both grid-tied and islanded operating mode. Control of real and reactive power realizing better power sharing during both grid-tied and islanded operating mode.

4.3.1. Droop control methods for hybrid microgrid The conventional power topology of hybrid AC-DC microgrid consist individual AC and DC sub-microgrids which are interlocked through IC. All distributed generations (DGs) supplying the hybrid AC-DC microgrid employed droop method for sharing AC and DC loads as reported in , , and .
The opportunity is present to interconnect DC microgrid and AC microgrid through an interlinking converter to form a hybrid microgrid when DC and AC microgrids are available in distribution generators. Adequate frequency/voltage control and power-sharing are the essential functions of DC and AC Microgrid control systems in a standalone mode.
