Prerequisite/Recommended prerequisite for
participation in the module
The module is based on knowledge achieved when studying the 2nd
semester on the Master of Science in Energy Engineering with an
electrical specialisation or Master of Science in Sustainable
Energy Engineering with specialisation in Offshore Energy Systems
or the Master of Science in Advanced Power Electronics.
Content, progress and pedagogy of the
module
Learning objectives
Knowledge
- Have knowledge about average and small-signal models for
voltage Source Converter (VSC) circuits including pulse-width
modulators and different output filters
- Understand impedance-based approach to get an insightful yet
easy-to-implement way for controller design and stability
assessment of VSCs
- Understand impedance-based stability analysis of grid
synchronisation and outer DC link voltage control loops
- Understand equivalence and differences between models
represented by single-input single-output complex transfer
functions and multi-input multi-output transfer matrices
- Have knowledge about passivity-based stability analysis and
control for robustly stable VSCs with different grid
conditions
- Have knowledge about virtual-impedance-based control for active
stabilisation and harmonic compensation of VSCs
Skills
- Be able to develop small-signal models for the
closed-loop-controlled VSC with closed correlations with
time-domain simulations
- Be able to design current controller, phase-locked loop, and DC
link voltage controllers under given dynamic specifications
- Be able to identify the causes of the different instability
phenomena of grid-connected VSCs
- Be able to design and implement different active damping
controllers for stabilizing VSCs
Competences
- Be able to deal with the instability problems in the emerging
VSCs-based power systems, which are nowadays commonly found in
renewable power plants, electric transportation systems, and
flexible ac/dc transmission/distribution systems
Type of instruction
The course is taught by a mixture of lectures, workshops,
exercises in simulations (PLECS) and experiments (dSPACE 1007).
Guest lectures relevant to the course will also be involved.
Extent and expected workload
Since it is a 5 ECTS course module, the work load is expected to
be 150 hours for the student.
