In integrated energy systems (IES)

the electric thermal hydrogen multi energy storage system has emerged as a key framework for achieving energy complementarity

improving energy utilization efficiency

and bolstering system flexibility and reliability owing to its distinctive advantages and potential.The primary concern is how to leverage the benefits of the electric thermal hydrogen multi energy storage system to enhance the systems load satisfaction rate

increase wind and solar energy absorption rate

and reduce system economic costs.This paper improves the operating model of the multi energy storage system by coordinating the scheduling of the self owned energy storage stations and shared energy storage stations within the integrated energy system and establishes an optimization model for energy storage capacity scheduling.Three optimization objectives are selected:load satisfaction rate

wind and solar absorption rate

and operational cost of the system.The penalty cost and improved radar chart based methods are used to calculate the objective function.The case study analysis using Matlab Cplex confirms that the energy storage capacity dispatch optimization model can significantly decrease the daily running costs of the system

enhance the absorption rates of wind and solar energy

and elevate the load satisfaction rate.
