Abstract: The integrated energy system with thermal energy storage device can realize the rational allocation of energy and effectively decrease the operation cost of the system. However, the introduction of thermal energy storage device increases the coupling strength and the variable dimension of the system, which makes the optimal scheduling of the system more difficult. To this end, this paper used energy hub for system modeling and introduce storage factor to describe the state of thermal storage device. Furthermore, a hierarchical scheduling strategy to solve the optimization model of the system was proposed. The energy hub scheduling layer is mainly used to solve the optimization scheduling problem of user energy need and energy hub; network optimization scheduling layer is mainly used to solve the optimal allocation problem of the energy transmission network. The case analysis shows that the hierarchical optimal dispatch strategy proposed can optimize reasonable scheduling of the system, allocate the resource rationally and reduce the energy cost.
