6 FAQs about [Microgrid coordinated control strategy]

What is a microgrid controller?

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.

How to coordinate power exchange between microgrids?

Microgrid cluster structure is proposed to coordinate power exchange among microgrids. Coordinated control method of PEU can realize mutual power support among microgrids. Coordinated control method of PEU can reduce the bus voltage and frequency deviation. Hierarchical coordinate control method of EP can stabilize the dc-link voltage.

How can power coordinated control improve the power supply reliability of microgrids?

Through the coordinate control among PEU, EP and microgrids, it can improve the power supply reliability of microgrid cluster and the energy utilization of RES. The proposed power coordinated control method of PEU can effectively realize mutual power support among microgrids and reduce the bus voltage and frequency deviation in each microgrid.

How can power management control a microgrid?

Majority of the researchers have proposed power management control aspects using decentralized or coordinated control strategies. While, the current strategies based on traditional controllers in microgrid are appropriate for voltage control, the inadequate control of frequency still exists.

How centralized control strategy is necessary for Microgrid cluster?

Therefore, the coordinated control strategy for the energy storage is necessary for microgrid cluster. For that, the centralized control strategies are implemented to realize the system net power distribution , . But all of these approaches need the critical communication devices, which degrades the reliability of system.

What is hybrid microgrid?
