4 FAQs about Distributed collaborative control of microgrids

What is distributed cooperative control of a dc microgrid cluster?

4. Implementation and validation The proposed distributed cooperative control of a DC microgrid cluster with multiple voltage levels connected by a MAB converter is validated on PLECS RT-Boxes which are hardware-in-the-loop (HiL) simulator and rapid control prototyping (RCP) of Plexim.

What is a dc microgrid cluster?

A DC microgrid cluster with three microgrids and a TAB interconnection converter is implemented in HiL. The real analog signals are sampled by the RCP and the PWM control signals are sent to HiL. With a low I/O latency, this experiment is comparable to a real physical system. Three DESs and a DG are deployed in each DC microgrid.

How does a dc microgrid work?

Within the DC microgrid, the renewable energy distributed generation (DG) generally operates in the maximum power point tracking (MPPT) state. Distributed energy storages (DESs) supply power when the DGs are insufficient to guarantee load power supply. When the DGs are sufficient, the power is stored by DESs to maximize economic benefits.

How do DC microgrids share energy?

The DC microgrids within the cluster are connected by a MAB converter. The proposed method not only realizes the distributed energy storage sharing among the microgrids, but also achieves load/source sharing and voltage recovery within a microgrid.
