[Objectives]In order to promote the efficient utilization of energy storage and user-side resources and improve the level of clean energy consumption,a multi-area interconnected integrated energy system planning model considering cloud energy storage was proposed.[Methods]On the basis of establishing the energy router model of the regional integrated energy system,a virtual energy router model considering electricity/heat/gas cloud energy storage was proposed.Aiming at the problem that cloud energy storage and integrated energy system belong to different investment entities,considering the limitation of the investment return period of cloud energy storage,a dual-subject two-stage planning model was proposed.In the first stage,the grid,equipment capacity and cloud energy storage price were planned.In the second stage,the operation strategy of the integrated energy system was optimized.Aiming at the high complexity of multi-energy flow grid planning,a pre-screening algorithm based on minimum spanning tree was proposed.[Results]The example analysis results of a three-park integrated energy system planning show that the proposed model is helpful to improve energy efficiency,reduce carbon emissions,and improve the economic benefits of interconnected integrated energy systems.[Conclusions]The research reveals the potential of collaborative planning between cloud energy storage and multi-area integrated energy systems,and provides reference for the in-depth application and commercial promotion of multi-type energy storage in the energy field.
