The integrated energy system, is to comprehensively plan, coordinately control, intelligently dispatch and multiply interact with multiple energy flows such as cold, heat, power and gas, which has broken the existing models of individual plan, design and operation of each energy supply system, and becomes a new model of future energy utilization. From the economic viewpoint, the energy storage system plays a quiet important role in this kind of grid structure. This paper presents a platform to assess the economic impact of different energy storage capacity and type on a district multi-energy grid operation cost. A multiple time-scale cooperative optimization is firstly proposed for the control optimization of energy storage, cold storage and heat storage to fulfill the minimization of total operation cost of integrated energy system. Then the economic benefits of different battery types and capacity are compared. For each scenario, the battery characterizes are also analysed and compared.
