Control of Bidirectional Quadratic DC-DC Converters for Storage Support of DC Power Grids
2018 7th International Conference on Renewable Energy Research and Applications (ICRERA), 2018Many applications require a DC bus supporting connections to several renewable energy sources, storage systems and loads. However, due to the intermittent nature of renewable energy sources and load variations it is essential to stabilize the voltage of the DC bus. Usually a battery is used to support the DC bus voltage, but their continuous charge and

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 ...

Multiport High-Power LCL DC Hub for Use in DC Transmission Grids
IEEE Transactions on Power Delivery, 2014This paper proposes an LCL dc hub concept which plays the role of a dc substation in a dc grid. The hub is capable of connecting multiple dc transmission lines with different dc voltages. Each dc transmission line can be added to or isolated from the hub without affecting the operation of the other dc transmission lines. The hub is based on multiple ac/
