Dual Two-Stage Isolated Bidirectional DC-DC Converter for DC Grid Storage
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018One of the trends for low-voltage dc grids is the use of a two-line dc distribution in order to facilitate the interface to present-time ac grids, and also to allow the flexible use of diverse loads. Another feature of such dc grids is the distributed storage elements in houses and buildings.

Combined DC Power Flow Controller for DC Grid
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018The utilization of DC power flow controller can increase the control freedom in the complex DC gird, which will improve both the active power distribution and coordination control performance of DC grid. The general concept frame of Combined DC power flow controller has been proposed in this paper, as well as a detailed topology.

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

Bidirectional non-isolated dc-dc converter for low-voltage DC-grid
2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016In this paper, a fourth-order non-isolated bidirectional converter is proposed for load power management in low-voltage DC grid. With state-space and discrete-time modeling technique, the proposed bidirectional converter is modeled, and small-signal transfer functions are obtained.

Power management in dc-grid through two-input dc-dc converter
2014 Eighteenth National Power Systems Conference (NPSC), 2014A new two-input dc-dc converter for power management in dc grid is presented in this paper. This two-input converter is evolved through the combination of Boost and SEPIC converter. Steady-state and state-space analysis is performed to understand the performance of the proposed converter and then to design appropriate digital controllers for better ...

A Transformerless High-Voltage DC–DC Converter for DC Grid Interconnection
IEEE Transactions on Power Delivery, 2018This paper presents a transformerless high-voltage dc–dc converter based on cascaded sub-modules. It is intended for interconnecting high-voltage or medium-voltage dc grids. The proposed dc–dc converter consists of two phase legs, each of which consists of an upper arm and a lower arm with their middle nodes crossly connected through a branch of active

DC/DC converter for high power DC grids
The present invention relates to a DC/DC converter which comprises a first bridge (Bridge 1) for connection via an inductor (L1) to a first DC power source (V1) and a second bridge (Bridge 2) for connection via an inductor (L2) to a second DC power source (V2). An AC transformer connecting the first and second bridges.Aboushady, Ahmed Adel Hassan Hassanein +1 more
