Wind power plant control and ancillary services
Control strategies for ancillary services from wind power plants which ensure stable operation of power systems with very high wind power penetration. This work includes dynamic modelling of wind turbines and wind power plant controls. Recent projects are EU ReservicES and the ongoing Danish REplan and NetVind. We are also leading the development of IEC standards 61400-27 Wind Energy Generation Systems – Electrical Simulation Models.
Wind power variability and uncertainty
We have developed and validated models to simulate wind power time series for generation and forecasts – taking into account the spatial and temporal correlations between wind power in power system areas. The models are implemented in CorWind, which can be accessed via a web account. The wind power time series are used in power system integration studies in European research projects on power system security (EU iTesla) and reliability (EU GARPUR) as well as commercially by European ENTSO-E and other transmission system operators e.g in Denmark and South Africa.
Grid connection of wind power plants
Our research in grid connection includes a number of power quality studies in Denmark as well as a research project on grid connection of wind power to weak grids in India. The research on grid connection is disseminated in consultancy related to development and maintenance of grid codes and through participation in IEC 61400-21 Wind Energy Generation Systems – Measurement and assessment of electrical characteristics.
Offshore HVDC and wind power
We are a key player in research projects dealing with offshore HVDC networks for combined grid connection of offshore wind power and interconnections between countries. DTU Wind Energy has lead the Nordic OffshoreDC research project, and is now leading two work packages in the EU PROMOTioN innovation project.
Wind power in island and isolated off-grid power systems
We provide assessment of the ability of an isolated power system to be able to integrate a significant amount of varying renewable energy. This involves studies tailored to the needs and characteristics of isolated systems (using DTU’s own IPSYS simulation software), assessment of technologies (e.g. control strategies, storage and load management), sizing of system components and requirements for project development. Project references include 4 island power systems in Cape Verde, Wind power in the Faroe Islands, Modular rural electrification in South Africa.
Short-Term Prediction and Possible Power
We have developed short-term prediction methods and software for decades, starting with Prediktor. Software has been implemented and run in projects in many countries, including Spain (research collaboration with CIEMAT), Ireland (with ESB), and in Texas and California (both with EPRI), Japan (Tokyo University), India, Taiwan and Turkey, Croatia and China. Prediktor was also used as the forecasting tool in CleverFarm to compare DMI-HIRLAM and the Deutscher Wetterdienst Lokalmodell. Prediktor is part of the Anemos collaboration. Ongoing research in e.g. the PossPow project is aiming at improving understanding and tools for modelling the behavior of wind farms in operation.

Data-driven solutions
As in many other fields, more and more data are being collected and made available in relation to energy systems. Such data may be used for developing dedicated visualizations, hence allowing to raise awareness (e.g., related to availability of renewable energy, CO2 emissions, etc.), but also for optimizating operation of energy systems.
