With the reform of the electricity market and the development of energy Internet technology

integrated energy system（IES）has been attracted important attention

and has the advantages of cleanness

high efficiency and high utilization rate of energy. Taking IES with multiple energy forms of industrial park as a study object

three alternative operation modes are proposed.Moreover

the influencing factors are analyzed

and the evaluation index system including economic

policy factors of user is proposed. The hierarchical structure model evaluation is established

and the optimal operation mode is selected according to the comprehensive weight through the analysis of the influence factors. Finally

taking the practical project of integrated energy system as an example

the comprehensive evaluation process of the operation mode is analyzed

which provides a reference for the development of IES in the industrial park.
