In order to further enhance the operating economy and low-Carbon characteristic of the integrated energy system

a low-Carbon and economic dispatch model for the island integrated energy system considering flexible response from source side to load side and new Carbon reduction mechanism is proposed. Firstly

a flexible dual response mechanism of supply and demand is introduced to improve economic efficiency

based on the comprehensive demand response characteristics of supply-side waste heat boiler

power-to-gas equipment and load-side. Additionally

acomprehensive satisfaction mechanism of electricity-heat-gas load is designed to accurately assess the satisfaction level of loads in the system. Secondly

in order to ensure the low-Carbon characteristic

a novel capture operation mode combining wind-light-Carbon capture is proposed to guide the wind and light to participate in the Carbon capture operation. At the same time

a ladder-type Carbon trading mechanism is introduced

and the low-Carbon characteristic model is constructed by combining the novel Carbon capture operation mode to realize the economic low-Carbon operation of the island integrated energy system. Finally

the CPLEX is used to solve the low-Carbon economic optimal model of the island integrated energy system to verify the effectiveness of the proposed model and algorithm. The data analysis shows that considering source-load response and new Carbon capture can reduce the operating cost of integrated energy system by 10.85%and carbon emissions by 55.58%.
