Transformer-based offshore electric-hydrogen hybrid landing

In recent years, offshore wind power has developed on a large scale. In order to reduce the dependence of long-distance power transmission on submarine cable laying, it has become a trend to promote local consumption of wind power through offshore P2H (Power to Hydrogen). However, differences in the transportation methods of offshore electricity and hydrogen resources will lead to significant delays between these two energy carriers. There is still a lack of effective methods to study the length of delay and the landing characteristics of mixed resources. In this paper, refined models for offshore electricity and hydrogen resource transportation are first constructed, and the pipeline hydrogen transmission delay is accurately evaluated using fin ite difference approximation. Then, a prediction method for electricity and hydrogen resources based on the transmission delay and Transformer model is proposed to clearly depict the boundary of resource mixed landing. Finally, an actual offshore wind farm example is used to verify that the proposed method can accurately predict wind power output and evaluate hydrogen transmission delay, and can provide a clear mixed boundary of electricity and hydrogen resources for landing point dispatching to promote consumption.
