Abstract Energy storage is the link of integrated energy system integration. How to allocate multiple types of energy storage is an important research content in integrated energy system planning. A collaborative energy storage configuration method for regional integrated energy systems considering differential modeling of electricity/heat/cold multi-energy storage is proposed. The basis of the multi-energy storage collaborative configuration is the description of coupling energy flow and energy storage characteristics. On the coupling energy flow, the integrated energy system structure containing three energy forms of electricity, heat and cold is defined, and the electricity-thermal network model is established. Based on the unified model of energy storage, the reactive power model of electrical energy storage and the refined model of thermal /cold energy storage were established, and the multi-energy storage comprehensive efficiency was defined to control the influence of different types of energy storage efficiency on the comprehensive energy utilization efficiency and economy. The multi-energy storage collaborative configuration model is established, which is used to get the multi-energy storage rated capacity, power and other planning schemes. With the goal of economy and environmental protection, it organically integrates the typical daily optimal operation. The hybrid algorithm combining genetic algorithm and Gurobi solver is used to solve the model. The example shows that the cooperative configuration and coordinated operation of multi-energy storage have advantages. Considering the unity and difference between multi-energy storage is helpful to get a more comprehensive energy storage configuration scheme.

Key words： Integrated energy system multi-energy storage of electricity/thermal/cold differential modeling of energy storage collaborative optimization configuration
