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。
