Two-input DC-DC converter for DC-Grid applications

2012 IEEE Fifth Power India Conference, 2012
A new two-input DC-DC converter suitable to draw power from two different dc sources feeding a common dc-bus is presented in this paper. This is a two-switch converter belongs to sixth-order family and performs bucking operation for one dc source while it allows both bucking as well as boosting feature with the second source. The salient feature of the

DC-DC converter for HVDC grid application

2017 National Power Electronics Conference (NPEC), 2017
There is an increasing interest in voltage source converter (VSC) based HVDC grids. The development of DC grids is likely to take place in phased manner with several voltage levels similar to that of the AC grids. These different high voltage DC levels will have to be interconnected with each other which will require DC-DC transformers.

DC bus strength in DC grid protection

2017 International Symposium on Power Electronics (Ee), 2017
Fast detection and isolation of DC faults is recognized as the main challenge in developing DC transmission grids. Voltage source converter blocking must be prevented which can be very difficult given the large rate-of-rise of fault currents. The concept of multi-converter DC bus is introduced as a grid design approach aimed towards increasing ...

DC/DC Converter for Integration of Renewable into DC mu-Grid

2022 IEEE International Conference on Environment and Electrical Engineering and 2022 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2022
This paper suggests a new high voltage gain DC-DC power electronics boosting converter. Many recent applications demand that an input voltage source is boosted to provide a much larger output voltage to be used elsewhere. The modern photovoltaic/fuel-cell sources or battery to mu-grid (mutext{-} grid) structure heavily depends on the voltage boosting ...

DC electric springs - An emerging technology for DC grids

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
There is widespread attention on integrating renewable energy sources, such as the solar power, to DC distributed power systems and DC microgrids. The voltage stability and the power quality issues are of concern if a large proportion of power sources in these DC power systems are generated by intermittent renewable energy sources.

Developing regional, radial DC grids and their interconnection into large DC grids

2014 IEEE PES General Meeting | Conference & Exposition, 2014
The development of future DC grids has high importance for future EU energy policy, but the technologies and DC grid topology are still uncertain. This article studies the concept of building large DC grids as an interconnection of regional radial DC systems. The radial topology enables very simple and robust DC system protection. It is not feasible to

Impact of DC-DC Converters for DC Grid Voltage Support

2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019
Modern power system is undergoing a gradual change from conventional sources of energy to renewable sources. This change requires restructuring of the power system so as to support the integration without compromising the security and stability. The power system itself is divided into smaller subsystems and the operation of these subsystems which are ...
