【摘要】 为实现电解铝综合能源系统（integrated energy system,IES）的低碳经济运行，提出了一种考虑需求响应（demand response,DR）与设备容量优化的IES低碳经济运行策略。首先，构建了融合电、热能源形式的IES拓扑，并基于电、热负荷可转移移特性，建立了其DR模型。在此基础上，构建了IES碳排放核算模型，并引入阶梯式碳交易机制进行碳排放约束。最后，以计及能源购买、设备运维、碳交易、设备投资和弃风弃光的综合成本为优化目标，构建以混合整数线性问题为描述形式的优化运行模型，并运用CPLEX进行求解。实验结果显示，优化目标考虑DR时，运行总成本和碳排放量分别下降了3.07%和1.17%。此外，在DR基础上进一步考虑设备容量优化后，运行总成本和碳排放量可额外下降0.39%和0.64%，同时保证了电解铝的产量。可见，所提方法可一定程度提高IES运行的经济性与环保性。更多还原

【Abstract】 In order to achieve the low carbon operation and economic benefits of integrated energy system(IES)in electrolytic aluminum, a low carbon economy operation strategy considering the demand response(DR)and equipment capacity optimization is proposed. First, an IES topology integrating electricity and heat energies is established, and a DR model is also established based on the transferability of electricity and heat loads. Then, the IES carbon emission accounting model is established, and a ladder-type carbon trading mechanism is introduced to implement the restriction of carbon emission. Finally, the optimization operation model is transformed in the form of mixed integer linear problem, which considers the comprehensive costs of energy purchase, equipment operation and maintenance, carbon trading, equipment investment and wind and light abandonment, and is solved by CPLEX. Experimental results show that when DR is considered, the total operation cost and carbon emissions are reduced by 3.07% and 1.17% respectively. In addition, after further considering the optimization of equipment capacity, the total operating cost and carbon emission can be additionally reduced by 0.39% and 0.64% respectively,while the production of electrolytic aluminum is ensured. As discussed above, the method proposed can improve the economy and environmental performance of IES operation to a certain extent.更多还原
