CANCELLED: Industrial/PhD Course: An Introduction to HVDC and MTDC Transmission System


02.10.2019 kl. 08.30 - 04.10.2019 kl. 16.00

This course introduces the HVDC transmission in power systems.

Line commutated converter (LCC) based High Voltage DC (HVDC) has been used worldwide for the transmission of bulk power over long distances. Voltage source converter-based HVDC (VSC-HVDC) transmission provides fast control of active and reactive power in all four quadrants. Nowadays, the concepts of multi-terminal dc (MTDC) grids interconnecting multiple energy resources and grids have been proposed.

A detailed description of the LCC-HVDC, VSC-HVDC (both using the two-level converters and the MMC-HVDC) and MTDC and their basic control schemes will be presented. The course will include lectures and simulation exercises. Simulation tools like PSCAD-EMTDC and DigSILENT will be used to demonstrate these applications.

Main topics are:

  • Limitations of ac power transmission and the need for HVDC
  • Classic HVDC transmission (LCC HVDC): Introduction, operation and control
  • VSC-HVDC transmission for the connection of relatively weak grids, and grid connection of renewable energy sources - Introduction, operation and control
  • Evolution of Modular multi-level converters (MMC) and MMC-HVDC - Introduction, operation and control
  • Multi-terminal DC transmission system


A basic knowledge of power transmission system and power converters.

Form of evaluation

The participants will have to write a report of the simulation exercises as a part of the course. Submission of this report via moodle is mandatory for the assessment and award of diploma.




6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry.
