Enhancing Offshore Wind Simulations: Interpolated Switching via DLL Black-Boxes
For power system engineers and OEMs, this work provides a practical method to enable detailed EMT simulations of IBR-rich systems while safeguarding proprietary information.
This paper addresses the challenge of protecting intellectual property while maintaining simulation accuracy in EMT studies of offshore wind farms. It proposes converting OEM models into DLL black-boxes with interpolation-based switching, achieving comparable accuracy to full-switching models without IP disclosure.
The modern power system, increasingly composed of Inverter-Based Resources (IBR) from multiple manufacturers, requires new study and design techniques that balance accuracy with the need to protect the Intellectual Property (IP) of various stakeholders. One possible method to support detailed electromagnetic transient (EMT) simulations is to convert the original equipment manufacturers (OEM) models into shareable black-box versions using dynamic link libraries (DLLs). This technique prevents IP violations while potentially maintaining simulation accuracy by embedding the original components within the shareable DLL. Thereby, this work aims explicitly to enhance simulation fidelity by translating full-switching models of offshore wind turbines (OWTs). In this context, the paper offers valuable recommendations, including how to convert interpolation-based elements, preserve simulation speed, recognize limitations, and outline future improvements
