Visual-oriented Safety Boundary Solving Method for Hydrogen Electric Coupling System

In this paper, the N-1 safety verification method and its corresponding safety boundary solving strategy are proposed. The feasible domain of the system is obtained based on the capacity of key equipment and pipe segments of the energy hub; the safety domain validation model of the hydrogen-electric coupling system is constructed, and the maximum energy-supply capacity, i.e., the safety domain, of each pipeline is obtained by iterative optimization using the binary interior point method. In order to further improve the visualization of data analysis, this paper reduces the dimensionality of high-dimensional pipeline load data to ensure the simplified presentation of complex data. The research in this paper provides effective theoretical support for the safety analysis of hydrogen-electric coupled system, which has important engineering application value and theoretical guidance significance.
