摘要:

基于“碳达峰、碳中和”背景,有效结合碳交易和绿证交易机制,挖掘需求侧资源,有助于实现综合能源系统低碳经济发展。为此,提出了计及灵活需求响应和阶梯碳-绿证联合交易的综合能源系统低碳优化调度策略。首先,在源侧引入含有机朗肯循环的余热发电环节,解耦热电联产“以热定电”约束,并在荷侧引入综合需求响应模型,构建了源荷协调的灵活需求响应模型。其次,研究碳交易和绿证交易机制原理,分析两者之间的相关性,构建了阶梯碳-绿证联合交易机制。最后,综合考虑系统经济性和低碳性,以总成本最低为目标,构建了日前低碳经济优化模型。算例仿真表明,考虑阶梯碳-绿证联合交易机制后系统总成本和碳排放量分别下降了13.37%和11.44%,并且相比传统需求响应模型,考虑所提的灵活需求响应模型后系统总成本和碳排放量分别下降了3.87%和2.85%,有效实现了系统经济、灵活和低碳运行。

Abstract:

Under the background of "carbon peaking and carbon neutrality", tapping the demand side resources with effective combination of carbon emission trading and green certificate trading mechanism will help to achieve the development of low-carbon economy in the integrated energy system. For this reason, this paper proposes a low-carbon optimal scheduling strategy for the integrated energy system (IES) considering flexible demand response and laddered carbon emission and green certificate joint trading. Firstly, a waste heat power generation link containing the organic Rankine cycle is introduced at the source side to decouple the constraint of "determining electricity by heat" for CHP, and an integrated demand response model is introduced at the load side, thus forming an flexible demand response model for source and load coordination. Secondly, the principles of carbon emission trading and green certificate trading mechanisms are studied and the correlation between the them is analyzed, and a ladder-type carbon emission and green certificate joint trading mechanism is constructed. Finally, taking into account both the economy and low-carbon performance of the system, a day-ahead low-carbon economic optimization model is constructed with the goal of minimizing the total cost. The simulation results show that the total cost and carbon emissions of the system have decreased by 13.37% and 11.44% respectively after considering the laddered carbon emission and green certificate joint trading mechanism. Compared with the traditional demand response models, the proposed flexible demand response model has reduced the total cost and carbon emissions by 3.87% and 2.85% respectively, effectively achieving economic, flexible, and low-carbon operation of the system.
