Abstract In view of the increasingly load fluctuation in power grid, the electro-thermal hybrid energy storage system was firstly proposed for peak-load shifting in integrated energy community, considering the deep coupling of multi-energy on the load side. Based on the hybrid operation model of battery and phase change material energy storage system, an electro-thermal combined peak-load shifting strategy was put forward with multi-attribute decision making, taking load variance and operation cost into consideration. The stochastic volatility model was used to forecast the load of the community, and the anti-risk ability of the proposed strategy to deal with load fluctuation was analyzed. According to the case study of a business community in Shenzhen, the electro-thermal hybrid energy storage system can making full use of the flexible bidirectional charging characteristic of battery energy storage and the long-term scale adjustment ability of phase change material energy storage. And the proposed strategy is capable of effectively promoting the ability of peak-load shifting and improving the operation economic benefits of the community on the premise of meeting the thermal demand of users.

Key words： Electro-thermal hybrid energy storage system phase change material energy storage system multi-attribute decision making electro-thermal combined peak-load shifting
