Integrated energy system has the characteristics of improving energy efficiency and being environmentally friendly. It has been developed rapidly in recent years

but it lacks technical and economic benefit analysis methods in its promotion process

and lacks typical representative reference cases. In order to solve the above -mentioned problems

a set of integrated energy system combining electric heat storage technology with wind power and photovoltaic is designed for knitting industry

and the benefits obtained after it is applied to the factory is analyzed. Finally

the electric heat storage technology is prospected. The results play an important role in promoting the application of electric heat storage technology and increasing the electrification rate of the terminal.
