An Optimal-Oriented Quasi-Droop Control of Interlinking Converter in Hybrid Microgrid [PDF]

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
In hybrid microgrid, interlinking converter (ILC) is a key component to connect the AC subgrid and DC subgrid. Its control strategy significantly affect the power flow management, power quality, system efficiency and stability. Traditionally, ILC is usually controlled as a current source, resulting in a poor dynamic stability when a remote weak AC ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Interlinking Converters for Hybrid AC/DC Microgrids: A Systematic Literature Review

IEEE Access
The interlinking converter (ILC) is responsible for performing the necessary conversions and managing the power flow between the AC and DC sub-grids of hybrid microgrid (HMG), which makes its full operation a critical factor for the performance of these ...

Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications

IEEE Transactions on Smart Grid, 2021
Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia levels and might lead to instability issues.

On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

Advanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Static Security Risk Assessment for Islanded Hybrid AC/DC Microgrid

IEEE Access, 2019
Due to the lack of the support from the main grid, the islanded hybrid ac/dc microgrid will more likely cause the power flow severe fluctuation and even the microgrid to be split once a serious contingency occurs.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Virtual Impedance Shaping for the Bus Conversion System in the Hybrid AC/DC Grid

IEEE Open Journal of Power Electronics
The bus conversion system in the hybrid AC/DC grid is usually composed of a three-phase interlinking converter and a DC-side input filter. The impedance interaction between the converter and the input filter may cause instability of the DC-link ...
