Abstract: Aiming at the cost and benefit problems in the operation of hydrogen containing integrated energy system, a commercial operation method of integrated energy considering energy supply mode is proposed. Firstly, considering each investor, two operation modes, multi link energy supply mode and multi-party cooperative energy supply mode, are proposed; Finally, the energy selling price of each company in the operation process is determined with the goal of the highest net income of the production capacity company and the energy supply company and the lowest price of each energy sold to users; The fast non dominated multi-objective optimization algorithm with elitist retention strategy (NSGA-II) is used to determine the Pareto solution set of the optimal price under each mode. Finally, the entropy weight method is used to determine the weight of each objective function, and the solution set of scheme 1 and 2 which are most popular among the three parties (energy supply company, capacity company and users) is selected, and then the optimal two modes of integrated energy system commercial operation are obtained.

Key words: hydrogen energy, integrated energy system, business operation mode, multi-objective optimization algorithm, entropy weight method
