Under the background of fast development of electricity demand-side response technique

the electric-power system of industrial park introduces different energy types such as gas

hydrogen to achieve comprehensive energy supply. As a result

the participation ability and intensity of demand-side response are significantly improved by the introduction of integrated energy system

and the utilization of renewable energy power is also promoted. In this study

the structure design and optimal dispatching of integrated energy system in industrial park under the background of electricity demand-side response are analyzed and researched

and the topology of integrated energy system including the thermal

electricity and hydrogen energy forms is developed. In addition

the optimal dispatching model is also established by introducing the complex constraints

in order to achieve economical operation of integrated energy system under the background of electricity demand-side response

in which the multi-energy loads are included. Experimental results show that the demand-side response participation of multi-energy loads can be effectively promoted by the introduction of integrated energy system

the operation cost can be reduced while the electric power demand during peak-period is decreased

and the utilization of renewable energy power is also significantly improved.
