Fast Power Flow Calculation Method for Electricity Hydrogen Storage Integrated Energy Network

Power system has developed significantly because of the increasing share of renewable energy sources (RESs). Despite the advantages, they also bring inevitable challenges to power system stability. Hydrogen energy plays an indispensable role in the process of energy transformation. This paper presents fast power flow calculation method for integrated energy network which contains PV, wind farm and hydrogen storage system. Energy hub model is developed to analyze the interaction between the power system and hydrogen system in steady-state operation. The mathematical model includes power grid, hydrogen network, PV and wind generation, hydrogen storage system, energy hub and power loss. Gauss-Seidel iterate method and Newton-Raphson method are applied to calculate the power flow calculation model of integrated energy system. Finally, a calculation example is used to verify the effectiveness of the proposed model and calculation algorithm.
