Welcome to Stability and Control of Grid-Forming Power Electronics Systems


Due to the rapid expansion of the renewable power generations, more unpredictable power is injected into the power grids through power electronics converters, which poses a great challenge to the safe operation of the modern power systems. Grid-connected converters are increasingly required to operate as grid-forming units for regulating the system voltage and frequency. The virtual synchronous machine technique makes converters mimic the self-synchronizing mechanism and the inertial response of synchronous machines, which provides a promising way to stabilize future power-electronic-based power systems. This course provides a systematic discussion on the fundamentals and state-of-art of grid forming power electronics systems in transmission and distribution systems. The main topics include:

- Basics of grid-forming power electronics systems
- Virtual synchronous machine control
- Inertia emulation and coordination with energy storage
- Fault ride-through and fault-current Limitation
- Small-signal modeling and stability analysis
- Design-oriented transient stability analysis
- Active damping of power oscillations

Prerequisites: Prior knowledge of power electronics fundamentals, feedback control theory, synchronous machines, and three-phase systems is preferred.

Important information concerning PhD courses We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
