2. Wind-turbine harmonic emissions and propagation through a wind farm
University dissertation from Luleå : Luleå tekniska universitetAbstract : The increasing demand for sustainable energy is one of the driving forces behind the increasing use of wind power by means of wind-turbines in electric power systems. Modern wind turbines commonly employ variable-speed-generator technology associated with a power-electronic converter as part of the grid connection. READ MORE

5. On Incentives affecting Risk and Asset Management of Power Distribution
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. READ MORE
