Wind Power Ramps: Characterisation, Forecasting and Future Projection

Offshore wind energy is a renewable energy source that is anticipated to be significant in the global shift towards clean and green energy in order to reduce the reliance on fossil fuels and mitigate climate change. In recent years, the overall output of offshore wind energy has increased, and as a result, investments in offshore wind power have...

Analysis and planning of power grids: A network perspective

Electric power has become an essential part of daily life: we plug our electronic devices in, switch our lights on, and expect to have power. As the availability of power is usually taken for granted in modern societies, we mostly feel annoyed at its absence and perceive the importance of power during outages which have severe effects on the...

Offshore wind power plants with VSC-HVDC transmission: Grid code compliance optimization and the effect on high voltage ac transmission system

The development of large offshore wind power generation in the North Sea has been significantly accelerated in the last years. The large distance from shore in combination with the need for large transmission capacity has raised the interest for the voltage source converter high voltage direct current technology (VSC-HVDC). Transmission system...

Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources: Theory and Applications

Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. However, due to the deregulation of electricity markets and the growth in the share of power generation by uncontrollable renewable energies such as wind and solar, power system simulations are more...

On the Dynamics and Statics of Power System Operation: Optimal Utilization of FACTS Devices and Management of Wind Power Uncertainty

Nowadays, power systems are dealing with some new challenges raised by the major changes that have been taken place since 80’s, e.g., deregulation in electricity markets, significant increase of electricity demands and more recently large-scale integration of renewable energy resources such as wind power. Therefore, system operators must make...

Wind power integration: From individual wind turbine to wind park as a power plant

As power capacities of single wind turbine, single wind park and total wind power installation are continuously increasing, the wind power begins to challenge the safety operation of the power system. This thesis focuses on the grid integration aspects such as the dynamic behaviours of wind power during disturbances, and dynamic behaviours of...

Power system operation with large-scale wind power in liberalised environments

Our society revolves around electricity. Most electricity is produced from fossil fuels, such as coal and natural gas. The disadvantages are that their supply is finite and unevenly distributed across the earth. Conventional power stations also emit greenhouse gases. Therefore, sustainable alternativees must be developed, such as wind power. The...

Integration of stochastic generation in power systems

Stochastic Generation is the electrical power production by the use of an uncontrollable prime energy mover, corresponding mainly to renewable energy sources. For the large-scale integration of stochastic generation in power systems, methods are necessary for the modeling of power generation uncertainty. In this thesis, new tools for the...
