    摘 要:装备电转气和碳捕集系统的热电联产机组参与的多能源系统是提升新能源消纳能力的有效解决方案,但热电联产的碳排放对系统的环境和成本提出了挑战。构建了含 CHP 模型及新能源的多能源系统框架并结合碳交易(CET)与绿色证书交易(GCT)交互机制,提出了一种快速求解计算量大的多能源系统优化调度问题的优化方法,降低系统的运行成本以及碳排放量。随着优化调度问题维度的增加,传统优化算法不能在短时间内作出适当的调度决策,提出了一种混沌蜣螂优化算法用于求解上述优化模型。算例结果表明,上述模型及方法可降低系统的成本和环境污染,进一步体现绿色优化调度的价值。

    Abstract: Multi-energy systems involving cogeneration units equipped with power-to-gas and carbon capture systems are an effective solution to enhance the capacity of new energy consumption, but the carbon emissions of cogeneration pose challenges to the environment and cost of the system. In this paper, a multi-energy system framework with CHP model and new energy is constructed and combined with the interaction mechanism of carbon emissions trading (CET) and green certificate trading (GCT), an optimization method is proposed to quickly solve the optimization scheduling problem of multi-energy system with heavy computation, so as to reduce the operating cost and carbon emission of the system. As the dimensions of the optimized scheduling problem increase, traditional optimization algorithms cannot make appropriate scheduling decisions in a short time. Therefore, a chaotic dung beetle optimization algorithm is proposed to solve the aforementioned optimization model. The case study results show that the above model and method can reduce the cost and environmental pollution of the system, further reflecting the value of green optimized scheduling.
    Key words: multi-energy system; cogeneration; carbon emissions trading mechanism; green certificate trading mechanism; dung beetle optimization algorithm
