Description

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.
