In view of at the problems of reactive power distribution and communication delay in isolated island microgrid, a hierarchical control algorithm based on consistency algorithm is proposed...
Dynamic consistency algorithms can be used to eliminate dependence on global communication, enable information sharing between distributed units, and reduce communication costs (Meng et al., 2014; Ma et
Various extensions to arc consistency are also possible. The domains need not be finite; they may be specified using intensions, such as 3 < X < 7.Higher-order consistency techniques, such as

To better adapt to the needs of the microgrid, it is considered to apply a distributed control algorithm based on finite time consistency to the hierarchical control of the microgrid. In the traditional microgrid control, to automatically realize the power distribution, the DC voltage control unit often adopts droop control.
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.
In order to solve the cooperative control problem among multiple distributed units in a distributed DC microgrid, a distributed control based on a consensus algorithm is firstly proposed, which can realize power distribution among distributed units.
The distributed control algorithm based on finite time consistency only needs to communicate with its neighboring agents to reach the consistency of the global state in a finite time, thereby realizing global control, and it can be fast, economical, and robust.
