为获得更好的经济效益和环境效益,提出了计及绿证-碳交易及综合需求响应的综合能源系统优化策略。首先,构建综合能源系统架构并对各设备进行建模;其次,分别建立绿证交易模型和碳交易模型;再次,根据可时移负荷建立综合需求响应模型,以系统总成本最小为目标建立优化调度模型;最后,运用CPLEX进行求解,通过对比分析验证所提策略的有效性。结果表明,计及绿证-碳交易及综合需求响应的综合能源系统优化模型极大降低了碳排放量,提升了系统的经济性。

In order to obtain better economic and environmental benefits,this paper proposes an integrated energy system optimization strategy that includes green certificate-carbon trading and integrated demand response.Firstly,the integrated energy system architecture is constructed and the models of each equipment are modeled.Secondly,the green certificate trading model and carbon trading model are established respectively.The comprehensive demand response model is established according to the time-shifting load.Thirdly,the optimal scheduling model established with the aim of minimizing total system cost.Finally,the CPLEX solver is used to solve the problem,and the effectiveness of the proposed strategy is verified through comparative analysis.The results show that the integrated energy system optimization model considering green certificate-carbon trading and integrated demand response can greatly reduce carbon emissions and improve the economy of the system.
