21. On maintenance optimization for offshore wind farms
Sammanfattning : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. LÄS MER
22. Voltage Support of Transmission Grids Using Resources Located in the Underlying Lower Voltage Networks : Unlocking the Potential of Distributed Generation Reactive Power Capabilities
Sammanfattning : The path to sustainable, fossil-free future leads to inevitable energy transition towards renewable energy sources. A part of this transition includes replacement of conventional transmission system connected power plants with distributed renewables plants such as wind power. LÄS MER
23. Load and risk based maintenance management of wind turbines
Sammanfattning : Wind power has proven to be an important source of renewable energy in the modern electric power systems. Low profit margins due to falling electricity prices and high maintenance costs, over the past few years, have led to a focus on research in the area of maintenance management of wind turbines.

24. Fault Behavior of Wind Turbines
Sammanfattning : Synchronous generators have always been the dominant generation type in the grid. This fact affected both planning and operation of power systems. With the fast increase of wind power share in the grid in the last decade, the situation is changing. In some countries wind power represents already a consistent amount of the total generation.

25. Dynamic Rating with Applications to Renewable Energy
Sammanfattning : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating. LÄS MER
