In order to achieve high consumption of new energy and reduce carbon emissions

this article closely links the power grid with heating network through electrolysis of water for hydrogen production and hydrogen methanation technology

as well as electric boilers and gas turbines

and other equipment. Firstly

model each unit in the integrated energy system. Secondly

introduce demand side response and divide it into price based demand response and substitution based demand response. Then

considering the energy flow characteristics of the system

constraints are imposed on the operating conditions of each unit. Finally

considering reliability

economy

environmental friendliness

and abandonment rate

a multi-objective comprehensive energy system capacity allocation strategy is established. On this basis

the commercial solver CPLEX in Matlab is used to solve the capacity configuration of the model

and the impact on the system capacity configuration with and without demand response and energy storage is analyzed. The reliability and economy of the configured capacity are verified using severe weather conditions. The results show that the capacity configuration can still have good economy and high wind and solar energy consumption rate with minimal load loss under adverse conditions.
