    摘 要:針對(duì)當(dāng)下能源系統(tǒng)的低碳性與經(jīng)濟(jì)性難以兼顧的難題,提出一種以熱電聯(lián)產(chǎn)機(jī)組為核心,耦合碳捕集與電轉(zhuǎn)氣設(shè)備,并計(jì)及液化天然氣冷能利用的新運(yùn)行模式?;谠撨\(yùn)行模式,構(gòu)建“源-荷”協(xié)同優(yōu)化的綜合能源系統(tǒng)低碳經(jīng)濟(jì)調(diào)度模型。以系統(tǒng)總成本最小為目標(biāo)函數(shù),“源”側(cè)采用新運(yùn)行模式的同時(shí),利用需求響應(yīng)策略使“荷”側(cè)可調(diào)度資源靈活化引入并參與低碳經(jīng)濟(jì)調(diào)度。以北方某地區(qū)綜合能源系統(tǒng)為例,基于 MATLAB/Yalmip 利用 Gurobi 求解器搭建并完成所提模型求解,分析各場(chǎng)景下模型碳排放、棄風(fēng)、棄光以及經(jīng)濟(jì)情況。算例表明,該模型有效降低系統(tǒng)碳排放,提升新能源消納空間并保證系統(tǒng)經(jīng)濟(jì)效益。

    Abstract: In order to solve the problem that it is difficult to balance the low-carbon and economic efficiency of the current energy system,a new operation mode with the cogeneration unit as the core, coupling carbon capture and power-to-gas equipment, and taking into account the utilization of liquefied natural gas cold energy is proposed. Based on this operation mode, a low-carbon economic dispatch model of integrated energy system with "source-load" collaborative optimization is constructed. In the model, with the minimum total cost of the system as the objective function, while the "source" side adopts the new operation mode, the demand response strategy makes the "load" side flexibly introduce and participate in the low-carbon economic dispatch. Taking a comprehensive energy system in a northern region as an example,based on MATLAB/Yalmip, Gurobi solver was used to build and solve the proposed model, and carbon emission, wind abandonment, light abandonment and economic conditions of the model were analyzed under each scenario. The simulation results show that the proposed model can effectively reduce the carbon emission of the system, improve the consumption space of new energy and ensure the economic benefits of the system.
    Key words: integrated energy system; low-carbon; carbon capture; demand response; carbon trade
