Abstract:
The presentation gives an insight into an RSCAD-based real-time digital simulation model of a 20 MW DC wind power generator integrated with an electrolyzer, highlighting control strategies for stability and efficient hydrogen production. The increasing demands for clean energy call for the development of large-scale systems that harness renewable energy with efficiency. This presentation showcases an EMT model of a 20 MW wind generation system rated at 100 kV for interconnection with HVDC. In this proposed system, an AC-DC and DC-DC converter combination provides seamless power transfer instead of the conventional back-to-back converter. It integrates an in-turbine electrolyzer with two operation modes, master and slave, focused on hydrogen production or grid power injection. This dynamic response has been verified on RTDS and proves the strategies and stability of control of the system. The model presented herein forms a basic building block within the design process of multi-gigawatt offshore wind plants with electrolyzers providing stability support to support flexibility in large-scale renewable energy applications in the future.
