摘要
为进一步提高园区综合能源系统的可再生能源消纳率以及系统的低碳性和经济性,提出了一种考虑绿证-碳交易机制和热电联产机组热电灵活响应的园区综合能源系统低碳经济调度策略。首先,通过绿色证书交易模型和阶梯式碳交易模型构建绿证-碳交易机制,旨在提高系统可再生能源消纳水平并降低系统碳排放量;其次,将有机朗肯循环引入系统,与传统的热电联产机组和电锅炉构建热电联产机组热电灵活响应模型,从而优化系统运行并为绿证-碳交易机制提供更大发挥空间;最后,以系统总成本最小为目标,构建考虑绿证-碳交易机制和热电联产机组热电灵活响应的园区综合能源系统优化模型。算例结果表明,该策略可提高系统的可再生能源消纳率,降低系统碳排放量和总成本。
In order to further improve the consumption rate of renewable energy and the low carbon and economy of the park integrated energy system(PIES),this paper proposes a low-carbon economic scheduling strategy for PIES,which considers the green certificate-carbon trading mechanism and the thermoelectric flexible response of combined heat and power(CHP)units.Firstly,a green certificate-carbon trading mechanism is established using the green certificate trading model and the stepped carbon trading model to improve the consumption of renewable energy within the system and decrease carbon emissions.Secondly,a thermoelectric flexible response model for CHP units is established by introducing the organic Rankine cycle into the system in combination with the conventional CHP units and electric boilers,thereby optimizing the system operations and providing greater application scope for the green certificate-carbon trading mechanism.Finally,with the goal of minimizing the total cost of the system,an optimization model of the PIES is constructed with consideration of the green certificate-carbon trading mechanism and the thermoelectric flexible response of the CHP units.The results show that the proposed strategy can improve the consumption rate of renewable energy,and reduce the carbon emissions and the total cost of the system.
