DC distribution systems and microgrids
2017The idea of merging variable sources with energy storage and controllable loads into flexible systems called microgrids (MGs) has been presented more than a decade ago [1]. MGs can operate autonomously or be grid-connected, and depending on the type of voltage in the point of common coupling (PCC), AC and DC MGs can be distinguished.

2015 IEEE First International Conference on DC Microgrids (ICDCM), 2015
This paper describes the behavior of voltage weak dc microgrids. These are dc microgrids with a relatively small system capacitance. The large amounts of stored energy in the passive component of a network has a considerable effect on the size of the fault currents, control and reliability.

2019 IEEE Third International Conference on DC Microgrids (ICDCM), 2019
A microgrid was developed as a modular “plug and play” system to accommodate both AC and DC loads up to a combined 125kVA total system power with a grid tie. A common DC bus configuration forms the backbone of the system, with bi-directional DC/DC and AC/DC power converters, allowing for a variety of renewable energy sources including PV arrays ...

Multi-port DC-DC converter for DC microgrid applications
2016 IEEE 6th International Conference on Power Systems (ICPS), 2016Multi-port DC-DC converters are gaining more prominence in interfacing multiple sustainable energy sources, storage systems and loads with one integrated topology. They feature reduced size, lower cost, better efficiency due to single power stage, faster response and compact centralized control.

Nonisolated High Gain DC–DC Converter for DC Microgrids
IEEE Transactions on Industrial Electronics, 2018DC microgrids are popular due to the integration of renewable energy sources such as solar photovoltaics and fuel cells. Owing to the low output voltage of these dc power generators, high efficient high gain dc–dc converters are in need to connect the dc microgrid.

High voltage gain DC-DC converter for DC microgrid
2017 International Conference on Intelligent Computing, Instrumentation and Control Technologies (ICICICT), 2017A group of non-isolated DC-DC high voltage gain converters for Dc micro grid is discussed here. The combination of non-isolated boost interleaved converter helps to obtain high step up gain without operating in a high duty ratio conditions. Through interleaved manner, a continuous current can be drawn from the given input sources.
