The top layer control is VSG control, and the lower layer control is droop control inside the AC/DC subnet. 18 The control strategy at the lower level belongs to peer-to-peer control. This means that all distributed power sources in the microgrid have equal control status, and there is no master–slave control relationship between controllers.

5 FAQs about [Wang Chengshan Microgrid Modeling and Control]

Who is Chengshan Wang?

Key Laboratory of Smart Grid of Ministry of Education, Tianjin University, Tianjin, China Chengshan Wang (Senior Member, IEEE) received the B.Sc., M.Sc., and Ph.D. degrees in electrical engineering from Tianjin University, Tianjin, China, in 1983, 1985 and 1991, respectively. He became a Full Professor with Tianjin University, in 1996.

How can a DC-DC converter based super-capacitor improve the inertia of DC microgrids?

To improve the equivalent inertia of DC microgrids (DCMGs), a unified control is proposed for the first time for a bi-directional DC-DC converter based super-capacitor (SC) system, whereby power disturbance smoothing and SC terminal voltage regulation can be achieved in a DCMG simultaneously.

Can low-voltage power cells be used as a microgrid?

Series connection of low-voltage power cells has been considered as an alternative microgrid configuration to supply rated voltage power to point of common coupling (PCC) loads. However, in the previous studies, the major focus was on the power regulation of system.

Is a decentralized interleaving PWM approach possible for parallel grid-tied converters?

A simple decentralized interleaving PWM approach is proposed for parallel grid-tied converters, in order to achieve significant reduction of switching current ripples at the point of common couplings (PCC).

Why is droop control used in multi-source multi-load DC microgrids?

[...] Droop control has been well adopted for multi-source multi-load DC microgrids (MGs) due to its inherent modularity and reliability by only using local measurements, especially with the most commonly-used voltage-current droop ( V-I ) mode.
