The basic idea of the content of this thesis work is described below. The details, however, will be discussed with the thesis worker in the beginning of the thesis work.

The main task is to investigate how an HVDC transmission can be used to improve stability margins in weak a.c. networks with a large amount of non-conventional generation (e.g. wind power and solar power).
A rough plan for the thesis work is given below:

1. Define and describe a test system for distribution of power with a relatively large portion of wind power imported or exported through an HVDC transmission system where the receiving grid has low short-circuit power (a weak a.c. system) and low amount of rotating mass (inertia).

2. Define key performance indicators (KPIs) to measure stability in any power system with respect to voltage stability, rotor angle stability and frequency stability. Propose how these KPIs can be measured and calculated for the defined test system.

3. Evaluate how the KPIs can be influenced by high level controllers in the HVDC transmission system such as power oscillation damping controllers, virtual inertia or coordinated control functionality with respect to the wind power.

4. Compare the increased stability margins that can be achieved by using the HVDC transmission instead of conventional methods using synchronous compensators.

The analysis can be expanded by adding a third converter in a three terminal configuration which for example can be located in a strong a.c. network.


Electric Power Engineering or Engineering Physics.
Knowledge within power system analysis, control theory and power system simulation software such as for example PSSE or PSCAD.

• Period: To be decided together with the applicant(s).
• Number of credits: 30 ECTS/högskolepoäng(hp)
• This thesis work is suitable to share between two students.
• The thesis work will be performed at ABB in Ludvika.
