摘要：
Firstly，the working characteristics of electrolyzers and fuel cells have been analyzed. A refined model of the hydrogen system equipment is built considering the dynamic efficiency. Secondly，the coupling relationship model between energy sources is constructed，the energy balance of the integrated energy system is realized by introducing multiple energy storages. Finally，a stochastic optimal scheduling model of the integrated electric-heat-gas-hydrogen energy system is established considering the fluctuation of load and the uncertainty of renewable energy. Case studies verify that the proposed optimization model can effectively consume wind and photovoltaic energy，reduce operation cost and mitigate environmental pollution. © 2023 Science Press.
