A dual three-phase induction machine based flywheel storage system driven by modular multilevel converters for fault ride through in HVDC systems
(
IEEE Computer Society
, 2016 , Conference Paper)
One of the main challenges of voltage source converter based high voltage direct current (VSC-HVDC) transmission systems is the AC faults at the grid side. This work introduces the integration of multiphase induction machine ...
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 Paper)
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 ...
A grid-connected HVDC shunt tap based on series-input parallel-output DC-AC multi-module 2-level voltage source converters
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Tapping-off a small amount of power from an HVDC transmission line to a three-phase local grid can be achieved by using shunt or series HVDC taps. This paper proposes a new grid-connected HVDC shunt tap. The proposed tap ...

Fault ride-through capability enhancement based on flywheel energy storage system for wind farms connected via VSC high voltage DC transmission
(
Institution of Engineering and Technology
, 2012 , Conference Paper)
This paper proposes a recovery strategy for wind energy-fed voltage source converter high voltage DC transmission systems, capable of maintaining power balance between the AC and DC sides during different AC faults. This ...
