With the increasing penetration rate of renewable energy generation and the rapid development of integrated energy system

an electric-thermal-hydrogen multi-energy storage（MES） optimized scheduling method is proposed.Firstly

the framework and equipment model of MES are established. On this basis

the influence of time-of-use pricing is taken into consideration

and a multi-objective optimal dispatch model of MES is proposed to achieve the unified effect of economy

efficiency and stationarity. The objectives of the model is to maximize the economic benefit

minimize energy loss and minimize power fluctuation between microgrid and external grid with participation of energy storage dispatching.Finally

a specific example is used to simulate and analyze the economic benefits of MES and the influence of energy loss and power fluctuation on economic benefits. The results show that the proposed model is scientific and effective.
