POSTPONED - Welcome to Grid-Forming Inverters: Principles and Practices
Description:
Inverter-based generation and transmission systems are vastly used in modern power grids, driven by the sharp cost reduction of renewable energy resources and the advances of power electronics technology. To secure a stable inverter-based power system, the grid-forming control is increasingly used with grid-connected inverters, who operate as voltage sources to regulate the grid voltage and frequency. There is thus an important need to address this timely and important topic among both power electronics and power system engineers and researchers. This course intends to provide a systematic discussion on the principles and design practices of grid-forming inverters. The main topics include, but not limited to
Grid-synchronization of inverters
From synchronous generators to grid-forming inverters
Overview of virtual synchronous generators
Synchronous power control – damping, inertia and virtual impedance
Small-signal modeling and stability analysis
Design-oriented transient stability analysis
Active damping of power oscillations
Day 1: From Synchronous Generators to Grid-Forming Inverters (Prof. Pedro Rodriguez, 6 hours)
- Grid-synchronization of inverters
- Fundamental concepts of grid-forming inverters
- Overview of virtual synchronous generators
Day 2: Synchronous Power Control (Prof. Pedro Rodriguez, 3 hours) and Voltage Control (Prof. Xiongfei Wang, 3 hours)
- Synchronous power control: principles and industry practices
- Damping, inertia and virtual impedances
- Design principles and practices of voltage control
- Small-signal modeling and passivity-based analysis
Day 3: Small-Signal and Transient Stability Analysis (Prof. Xiongfei Wang, 6 hours)
- Small-signal modeling of power control
- Analysis and damping of synchronous resonance
- Analysis and damping of sub-synchronous resonance
- Large-signal modeling of power control
- Transient stability analysis
Prerequisites:
Prior knowledge on the fundamentals of power systems and synchronous machines, power electronics, as well as feedback control theory are 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 four 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.
