doi:10.16182/j.issn1004731x.joss.22-0189

Abstract

Abstract:

With the development of the electricity market and carbon market,the introduction of demand response and carbon trading mechanisms into the operation and dispatch of integrated energy systems will help guide users and system operators to optimize electricity consumption and dispatch plans.The comprehensive incentive measures such as time-of-use electricity prices and demand response incentive subsidies are used to guide users to participate in demand response.A two-layer stochastic optimal scheduling model for a comprehensive energy system considering the ladder-type carbon trading mechanism and demand response is constructed based on IGDT (information gap decision theory) theory.The two-layer model is converted into a single-layer model by KKT condition and big M method for solving.The results show that the introduction of the demand response and carbon trading mechanisms can achieve low-carbon and environmentally friendly operation of the integrated energy system.

Key words: integrated energy system, demand response, IGDT, ladder-type carbon trading mechanism, two-layer model
