Abstract: A low-carbon economy dispatching method for the integrated energy system of the park taking into account the demand response ratio is proposed. First of all,the optimal dispatching model of the park’s integrated energy system is established,and the traditional and stepped carbon emission trading mechanism,the traditional and stepped comprehensive demand response compensation mechanism are modelled. Secondly,different scenarios are set according to different carbon emission trading and comprehensive demand response compensation mechanisms,and CPLEX solver is used to solve the model. Finally,the impact of different carbon emission trading and comprehensive demand response compensation mechanisms on system operating costs and carbon emissions are analyzed to propose low-carbon economy indicators for system operation,and on basis of that to analyze the low-carbon economy of the system under different demand response ratios. The results show that the stepped carbon emission trading mechanism and comprehensive demand response can effectively improve the environmental protection and economy of the system. After the introduction of the stepped comprehensive demand response compensation mechanism,the low-carbon economy index of the system is the lowest when the demand response ratio is 20%.
