Microgrid switching topology consistency

How to improve microgrid control?

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.

Does communication topology influence the microgrid system?

In , considering the influence of the transformed communication topology on the microgrid, a distributed cooperative control method based on two-level multi-agent system (MAS) was proposed, which enabled the microgrid system to ensure good global voltage regulation and uneven unit current sharing.

How to solve Island microgrid secondary control problem under time-varying topology?

In , in order to overcome the problem of island microgrid secondary control under time-varying topology, the cooperative fault-tolerant control algorithm was proposed to keep the system stable under actuator failure and time-varying directional communication network.

What is dc microgrid topology?

DC microgrid topology. DC microgrid has just one voltage conversion level between every dispersed sources and DC bus compared to AC microgrid, as a result, the whole system’s construction cost has been decreased and it also simplifies the control’s implementation , .

How to solve cooperative control problem in a distributed dc microgrid?

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.

What is the optimal control strategy for AC/DC hybrid microgrid groups?

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.
