1. Wind Turbine Models for Power System Stability Studies
Sammanfattning : The purpose of this thesis is to develop dynamic models of wind turbines for power system stability studies. More specifically, the wind turbine models are mainly intended for voltage and frequency stability studies. LÄS MER
2. On the modelling and partial-load control of variable-speed wind turbines
Sammanfattning : .... LÄS MER
3. Steady state analysis of HVDC grid with Wind Power Plants
Sammanfattning : The idea of building a multi-terminal, even a meshed HVDC grid in the North Sea, that can inter-connect surrounding nations, is being discussed widely. Such a system is expected to be realised in steps through the interconnection of wind power plants and electricity markets. LÄS MER
4. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation
Sammanfattning : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. LÄS MER
5. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing
Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER
