Protective Systems in DC Microgrids
2019The aging power system causes to several grid problems such as intermittency, power quality issues, and blackouts since a few decades. Therefore, the power infrastructure requires serious troubleshooting studies in a wide manner. The distributed generation and integration of large photovoltaic (PV) plants to the existing utility have led to intensive ...

Overview of multi-DC-bus solutions for DC microgrids
2013 4th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2013DC Microgrids have recently received a lot of attention in the last years due to high penetration of renewable energy sources as well as distributed energy storage systems. In the future DC microgrids could be preferable respect to AC microgrids in terms of redundancy since multi-DC-Bus solutions could provide a continuative power supply to the loads ...

Fault tolerant DC-DC converters in DC microgrids
2017 IEEE Second International Conference on DC Microgrids (ICDCM), 2017The deployment of DC microgrids proves to be an excellent opportunity to significantly increment the energy efficiency in buildings. Among other components, DC-DC converters play vital functions in a DC microgrid. However, the reliability levels of these energy conversion solutions are still quite limited.

Consensus only control in DC microgrids
Proceedings of the Ninth International Conference on Future Energy Systems, 2018Voltage droop control for DC microgrids has limited power/current sharing capabilities. Although droop complemented with a consensus control loop can achieve desired power/current sharing, the resulting voltage deviation may need correction. We propose a consensus only control that achieves proportional current sharing and simultaneously avoids large ...

AC Versus DC Microgrid Planning
IEEE Transactions on Smart Grid, 2017This paper presents a microgrid planning model for determining the optimal size and the generation mix of distributed energy resources (DERs), as well as the microgrid type, i.e., ac or dc. Considering the growing ratio of dc loads and DERs, dc microgrids could be potentially more beneficial than ac microgrids by avoiding the need to synchronize ...
