摘要
智慧园区工业用户用能量较大,自动化水平高,且能源耦合紧密,在参与碳排放削减和需求响应中扮演了重要角色。从工业用户的角度出发,针对用户上级购电来源不同,将满足上级削峰指令设置为内部优化目标,将用户的日运行成本最低设置为外部优化目标,在此基础上建立了考虑阶梯式碳交易机制下用户参与综合需求响应的混合整数非线性优化模型,通过将其转换为混合整数线性规划问题并对其求解,最终得到用户在传统经济调度和参与综合需求响应两种模式下的运行策略。算例分析表明,所提出的策略可进一步提高园区用户的低碳性和经济性,并为用户在不同模式下参与需求响应提供了不同的响应策略。在阶梯式碳交易机制下,用户的需求响应方式转变为热需求响应优先,使得用户在完成削峰目标的同时降低碳减排放和运行总成本。
The industrial users in the smart park use more energy,have a high level of automation,and are closely coupled with multiple energy sources.They play an important role in participating in carbon emission reduction and demand response.Consequently,different power sources of industrial users are taken into consideration,the peak-shaving instruction from senior authorities is set as the inner optimization target,and the lowest daily operating cost of the system is set as the outer optimization target,so that a mixed-integer nonlinear optimization model is established that considers user participation in comprehensive demand response under a stepped carbon trading mechanism model.Furthermore,the model is converted into a mixed-integer linear programming problem which is solved.Finally,the user’s operating strategy in two modes of traditional economic dispatch and participation in comprehensive demand response can be obtained.The analysis of calculation examples shows that the proposed strategy can further improve the low carbon and economical efficiency of users in the park,and provide different response strategies for users to participate in demand response in different modes.Under the step-by-step carbon trading mechanism,user’s demand response method is changed to thermal demand response priority,enabling users to reduce carbon emissions and total operating costs while achieving the peak reduction target.
