Thepolicy environment tends to be favorable, while the economic environment seems worrisome. The latter ismainly due to energy transportation blocking and price escalating. The paper also introduces the performanceand development of listed power companies, and points out that the power stock market is still promising andpower industry is still valuable for investment.展开更多
“双碳”目标下,为进一步降低综合能源系统(integrated energy system,IES)碳排放,提升可再生能源消纳能力,提出一种IES低碳经济运行优化策略。首先引入阶梯型碳交易机制约束IES的碳排放;然后建立耦合电转气(power to gas,P2G)和碳捕集...“双碳”目标下,为进一步降低综合能源系统(integrated energy system,IES)碳排放,提升可再生能源消纳能力,提出一种IES低碳经济运行优化策略。首先引入阶梯型碳交易机制约束IES的碳排放;然后建立耦合电转气(power to gas,P2G)和碳捕集系统(carbon capture system,CCS)模型,并细化P2G两阶段运行;接着在传统热电联产机组(combined heat and power,CHP)中引入卡琳娜循环与电锅炉联合运行,构造热电灵活输出的CHP模型;最后以系统运维成本、碳交易成本、购能成本和弃风弃光成本之和最小为优化目标,构建IES低碳经济调度模型,并设置不同运行场景对比分析。结果表明:IES碳排放减少38.45%,运行总成本降低10.37%,验证了所建模型的低碳性和经济性。展开更多
