Integrated energy system is an effective solution to solve the problems in the current energy field. Gas, electricity,heat, cold and other forms of energy storage play important roles in IES. An integrated energy storage optimization configuration model is proposed, which can be widely applied to multiple IES architectures. The universality of the model is also analyzed. Firstly, a universal model of user side IES is established. Secondly, based onthe universal model of IES, an integrated energy storage optimization configuration model is established to make the configurationmodel applicable to various IES architectures. Aimed at minimizing the annual cost of system life cycle, the model determines the configuration capacity and power of various energy storage. Finally, a case study of IES in a commercial building is analyzed. And the universality of the optimization configuration model in other scenarios is analyzed. The result shows that the proposed model can be applied to IES of multiple architectures to solve the problem of optimal configuration of integrated energy storage in different scenarios.
