Lowcarbon development of the power industry is an important measure for the dualcarbon goal. In order to promote carbon emission reduction and improve the economy, reliability and environmental protection of the multienergy system, an optimization model for the carbon emission reduction of the multienergy system considering the coordination of economy and reliability is proposed in this paper. Firstly, the coordination model of LowCarbon MultiEnergy System (LCMES) is established by analyzing the topology of the LCMES including electricity, gas and heat; Secondly, based on the fault characteristics of the energy conversion and storage equipment in the LCMES, the multistate reliability model of the LCMES is established; Then, under the conditions of operation constraints and reliability constraints, an optimization model of carbon emission reduction of the LCMES considering the coordination of economy and reliability is proposed with the objective of minimizing the operation cost and carbon emissions of multienergy system; Finally, it is verified by simulation numerical example that the multienergy system optimization model proposed in this paper can ensure the improvement of the operation reliability and economy of the multienergy system while achieving the carbon emission reduction.
