Analysis and modeling of unsteady aerodynamics with application to wind turbine blade vibration at standstill conditions
Since the introduction of computational models for the dynamic aeroelastic response of wind turbines, numerous dynamic issues have been investigated to assist in understanding and overcoming problems as well as help designing reliable turbines. In some cases specific problems have necessitated evolution of new or improved sub-models in the aeroelastic computational tools, such as for instance the so called dynamic stall models that models the dynamic aerodynamic response from the onset of separation until the flow over the airfoil is fully separated.
he main objective of the project is to promote wind energy development and facilitate investments on wind energy projects in Cambodia, the Philippines and Vietnam through feasibility assessment and capacity building.

Additionally, the objective is to develop calculation and design tools for development and evaluation of very large wind turbines based on this concept.

OffshoreDC: DC grids for integration of large scale wind Power 
The future wind power development in the Nordic region will to a large extent be based on offshore wind power plants. Several studies have indicated that it is advantageous to combine the grid connection of offshore wind power plants with interconnections in large offshore grids. 
HVDC technology is already widely used for interconnection between power system areas, enabling power transmission over long distances without sub stations. The future large offshore grids will require complex network topologies with multiple connection points to make possible the combination of offshore wind power plants grid connection with increased interconnection capacities in large offshore grids. 
The overall objective of the project is to identify and pursue solutions to offshore HVDC grids and their functionality as means of integrating large amounts of offshore wind power.

Structural Blade Design and Testing 
With the explosive growth within wind energy, more research is needed in the area of structural design and testing of wind turbine blades. When the blade design is up-scaled without optimization, its weight increases cubically with respect to the performance. Therefore it is crucial to optimize the design of  future blade. The main focus is to try to understand why and where the blades fail and then improve the design accordingly. A combination of experimental and numerical studies is used to address the most critical failure mechanisms observed during full-scale tests and the corresponding.

The Bolund experiment is a field campaign that provides a new dataset for validating models of flow in complex terrain. It has been the basis for a unique blind comparison of flow models.

CFD is becoming a standard tool to quantify such wind conditions and determine the optimum positions of the wind turbines. However, these flow models have usually only been validated against wind tunnel experiments with simple terrain forms.
