电力行业的低碳化发展是实现“双碳”目标的重要举措,为促进碳减排,实现多能源系统在经济性、可靠性、环保性方面的提升,文章提出了一种考虑经济性与可靠性相协调的多能源系统碳减排优化模型。首先,通过分析含电、气、热的低碳多能源系统(Low-Carbon Multi-Energy System,LCMES)拓扑结构,建立LCMES协调模型;其次,基于LCMES内各能源转换和存储设备故障特点,建立LCMES的多状态可靠性模型;再次,在LCMES可靠性约束和运行约束条件下,以LCMES的运行成本和碳交易成本最小为目标提出了考虑经济性与可靠性相协调的多能源系统碳减排优化模型;最后,通过算例仿真验证了文章提出的多能源系统优化模型能够在实现碳减排的同时,保障多能源系统运行的可靠性及经济性的提升。

Low-carbon 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 multi-energy system,an optimization model for the carbon emission reduction of the multi-energy system considering the coordination of economy and reliability is proposed in this paper.Firstly,the coordination model of Low-Carbon Multi-Energy 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 multi-state 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 multi-energy system;Finally,it is verified by simulation numerical example that the multi-energy system optimization model proposed in this paper can ensure the improvement of the operation reliability and economy of the multi-energy system while achieving the carbon emission reduction.
