In order to build a low-carbon sustainable energy system and promote the transformation of energy system, this paper focuses on low-carbon and clean energy systems, and establishes a day-ahead dispatch model of an electricity-gas-heat-hydrogen integrated energy system that considers economy and carbon emissions. Firstly, in the integrated energy system network, the power flow model of the power grid and the dynamic power flow models of the heating network and the gas network are established considering the load uncertainty. Considering the advantages of clean, high-efficiency and safety of hydrogen energy in energy conversion equipment, power to hydrogen (P2H) equipment and hydrogen energy storage equipment are introduced. Taking into account the waste heat of gas turbines, fuel cells, etc., the organic Rankine cycle (ORC) waste heat power generation is introduced to convert the remaining heat energy into electric energy and improve energy utilization efficiency. Secondly, the system operating cost and environmental cost are considered as the objective functions. Then the optimal operation dispatching plan is put forward for the electricity-gas-heat-hydrogen integrated energy system. Finally, this paper conducts simulation analysis for multiple optimized operation modes. The simulation results show that the optimized operation strategy of the electricity-gas-heat-hydrogen integrated energy system proposed in this paper can effectively ensure the economic and environmental protection of operation.

Key words: electricity-gas-heat-hydrogen, integrated energy system, carbon cost, optimal operation
