DC/DC converter for offshore dc collection grid
International Conference on Renewable Power Generation (RPG 2015), 2015Offshore wind represents a significant clean energy resource. Current offshore wind farm designs use a conventional AC collection network in which the wind-turbine AC output voltage is stepped up to a medium-voltage suitable for wide area connection. A DC offshore collection grid offers an attractive alternative to an AC architecture as it avoids the ...

A Bidirectional Isolated Multiport DC-DC Converter for DC grid
2021 IEEE Southern Power Electronics Conference (SPEC), 2021Multiport DC/DC converters (MPC) is becoming a promising configuration to integrate DC grids with different voltage levels. This paper presents a neutral-point clamped (NPC) converter-based MPC (NMPC), which is developed to interconnect medium voltage DC (MVDC) grid and low voltage DC (LVDC) grid. The circuit topology and operation principle of NMPC is

Developing regional, radial DC grids and their interconnection into large DC grids
2014 IEEE PES General Meeting | Conference & Exposition, 2014The 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

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), 2022This 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), 2015There 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.

IoT-Grid: IoT Communication for Smart DC Grids
2016 IEEE Global Communications Conference (GLOBECOM), 2016IoT technology is considered an essential imperative for Smart Grids (SGs). However, IoT devices have inherently limited responsiveness that may not be sufficient for a time critical SG with stringent demands on communication delay. In practice, it remains an outstanding problem to combine IoT technology with existing grids. To facilitate deployment of

DC-DC converter for HVDC grid application
2017 National Power Electronics Conference (NPEC), 2017There 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.
