(
MDPI
, 2022 , Article)
The COVID-19 pandemic has brought several global challenges, one of which is meeting the electricity demand. Millions of people are confined to their homes, in each of which a reliable electricity supply is needed, to ...
Multiloop control strategy for grid-interfaced three-phase voltage source inverter with passively damped LLCL-filter
(
Institution of Engineering and Technology
, 2014 , Conference)
In inverter-based distributed generation (IBDG) and similar to the conventional third order LCL filter, the high order LLCL filter is difficult to stabilize, and may cause a resonance between the inverter and the grid. ...
Medium voltage flywheel energy storage system employing dual three-phase induction machine with machine-side series-connected converters
(
Institution of Engineering and Technology
, 2014 , Conference)
Flywheels as energy storage systems are good candidates for numerous power system applications such as voltage support, serving fluctuating loads, frequency regulation and renewable energy utilization. Most of these ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
Traction system with on-board inductive power transfer
(
Institution of Engineering and Technology
, 2014 , Conference)
In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide ...
Torque ripple reduction of radial magnetic gearbox using axial pole pairing
(
Institution of Engineering and Technology
, 2014 , Conference)
Magnetic gearbox (MGB) is a contactless magnet-based transmission system that transmits mechanical power between two shafts. MGBs offer significant advantages over mechanical gears such as contactless power transfer, high ...
Performance assessment of single and dual loops discrete PR controllers with LCL filter for inverter-based distributed generation
(
IEEE Computer Society
, 2014 , Conference)
Due to the rapid growth of the electric energy demands, the necessity of involvement of distributed generation (DG) to overcome this demand became a must. When distributed generation renewable energy sources are coupled ...
A new protection scheme for HVDC converters against DC-side faults with current suppression capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Two-level voltage-source converters and half-bridge modular multilevel converters are among the most popular types of HVDC converters. One of their serious drawbacks is their vulnerable nature to dc-side faults, since the ...
