Operation of the full‐bridge three‐level DC–DC converter in unbalanced bipolar DC microgrids

IET Power Electronics, 2019
As compared to two‐wire, unipolar DC microgrids (DCμGs), bipolar DCμGs apply a positive, neutral and negative conductor to increase the power transfer capability while retaining two voltage levels for supplying low‐ and high‐power devices at an appropriate voltage.

Linearised Bipolar Power Flow for Droop-controlled DC Microgrids

2021 International Conference on Engineering and Emerging Technologies (ICEET), 2021
The increase in efficiency and easiness to connect renewable energy sources has brought an increased interest into DC microgrids. Bipolar DC microgrids, present advantages over unipolar DC microgrids. Yet, due to their configuration they are prone to suffer from asymmetric loading which results in voltage unbalances among poles.

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
