Abstract
An open-source wind turbine controller, DTU Wind Energy Controller (DTUWEC), developed by Technical University of Denmark (DTU), is presented. The DTUWEC includes many advanced features and it is publicly available to the wind energy community. It is envisioned that this research work converts the old version of Basic DTU Wind Energy Controller into a generic, powerful and robust open-source wind turbine controller with a large number of developers and users in both research institutions and industries. DTUWEC is implemented in Fortran and offers the DNV-GL Bladed/OpenFAST style interface. Because of its open-source and modular characters, researchers are able to couple DTUWEC with different aero-elastic simulation codes to investigate the effect of different controllers on the wind turbine structural loads and power output, and to collaborate for future potential improvements.
Highlights
The development and improvement of wind turbine aero-servo-elastic simulation software have been one of the main activities within wind turbine research institutes, manufacturers and consulting companies for the last thirty years

The research achievements resulted in the first version of the Basic DTU Wind Energy Controller developed by Hansen and Henriksen [1], which was released as an opensource controller built for high fidelity in-house aero-elastic simulation software HAWC2 [2] in 2013
Summary
The development and improvement of wind turbine aero-servo-elastic simulation software have been one of the main activities within wind turbine research institutes, manufacturers and consulting companies for the last thirty years. Modularizing the wind turbine simulation software becomes increasingly crucial for (i) motivating module sharing across the wind turbine community; (ii) simplifying the procedure for code verification; (iii) improving model performance and (iv) enhancing the flexibility and expandability to enable cross developments of functionalities among the wind energy community. The research achievements resulted in the first version of the Basic DTU Wind Energy Controller developed by Hansen and Henriksen [1], which was released as an opensource controller built for high fidelity in-house aero-elastic simulation software HAWC2 [2] in 2013. Several advanced control features such as Individual Pitch Controller (IPC) [3], Individual Flap Controller (IFC) [4] and integrated flap controller [5, 6] were implemented as individual modules of the Basic DTU Wind Energy Controller for many externally funded research projects.
