Controlled Power System Separation Using Generator PMU Data and System Kinetic Energy

With the growing number of severe system disturbances and blackouts around the world, controlled system separation is becoming an increasingly important system integrity protection scheme (SIPS) to save the electric power system from a complete or partial disintegration. A successful controlled splitting approach should at least tackle the...

Hardware-in-the-loop based testing of wind turbine controllers for transient stability enhancement

Traditionally, electrical power systems have been based on fossil-fuel fired generation plants to satisfy the load demand. However, due to environmental targets for significant CO2 reduction, a gradual decommission of the aforementioned plants is observed whereas renewable energy sources are gaining gradually increasing momentum, which entails...

A Fundamental Study on the Transient Stability of Power Systems with High Shares of Solar PV Plants

The last decade has seen an immense growth in renewable energy sources such as solar photovoltaic (PV) plants due to environmental concerns. Due to this rapid growth, solar PV plants are starting to have a larger influence on power system stability and thus their dynamic behavior cannot be ignored in stability studies. The lack of well...

Modelling Regional Power Grids for Large-Disturbance Stability Studies

Due to the shift in electrical energy generation from thermal synchronous generators towards various renewable sources, power system stability will become a more pressing issue in the near future. In this thesis, we explore possible improvements to the dynamic grid model currently used by TenneT TSO for large-disturbance stability studies,...

Evaluation of frequency and transient stability indicators in future power systems with high levels of wind power generation

This master thesis analyses different ways to perform assessment in frequency and transient (rotor-angle) stability when high penetration of renewables exists in the grid, based on researches done in the academic world and in industries. The goal of this research focuses on assess the distance to frequency and transient instability in power...
