Abstract: The high-speed railway station contains various loads such as cooling, heat and electricity, which is a typical application scenario of the integrated energy system （IES）. At the same time, compared with conventional industrial parks, a high-speed railway station as a giant cavity building has good energy storage characteristics. In view of the planning of a new high-speed railway station, this paper proposes an optimized planning method for integrated energy system considering the energy storage characteristics of buildings. Firstly, the energy supply framework of the integrated energy system is established. On this basis, considering the building characteristics and the controllability of the temperature inside the station, the model of the energy storage system is built, and the corresponding comfort cost is considered. Then the model is integrated into the integrated energy system framework. The overall planning takes the total annual cost as the optimization goal and the system is optimized by a two-layer optimization method. The simulation results show the effectiveness and rationality of the proposed method.
