6 FAQs about [Microgrid Convergence]

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.

Does convergence time of consensus algorithm affect transient stability of microgrids?

Convergence time of consensus algorithm significantly affects transient stability of microgrids, due to changes in communication topology, switching of distributed generations (DGs), and uncertainty of intermittent energy sources.

Does a wave energy conversion system work in a microgrid?

To see the effect of the Wave energy conversion system and capacitor energy storage system (CESS) integration in a microgrid, various cases of disturbances are taken with the proposed optimization technique and controller.

Do microgrids have a conflict of interest?

No conflict of interest has been declared by the authors. The secondary control layer of microgrids is often modelled as a multi-agent distributed system, coordinated based on consensus protocols. Convergence time of consensus algorithm significantly affect...

How do Hybrid microgrids work?

Microgrids are connected together using ILC devices, through which any two DGs in a hybrid multi-microgrid system can communicate with each other and react according to the current generation and load of each microgrid. It provides the communication network foundation for the distributed control between and within AC/DC hybrid microgrid.

Can the frequency synchronization be maintained in a microgrid system?

In the face of load changes, the frequency of each DG in the microgrid will fluctuate correspondingly, but the frequency synchronization can always be maintained. The strategy in Fig. 5 b cannot restore the system frequency to the rated reference frequency of 50 Hz, and the microgrid system cannot maintain stable operation for a long time.
