为有效提高碳排放配额分配的合理性,并且避免年度结算时碳排放量超标导致环境污染加剧问题,提出基于奖惩因子的季节性碳交易机制,以园区综合能源系统(park integrated energy system,PIES)为对象进行低碳经济调度.首先,构建包含能量层-碳流层-管理层的综合能源系统(integrated energy system,IES)运行框架,建立电气热多能流供需动态一致性模型;其次,分析系统内"日-季节-年度"碳排放特性,打破传统应用指标法的配额分配方法,采用灰色关联分析法建立碳排放配额分配模型,并基于奖惩阶梯碳价制定季节性碳交易机制;最后,以系统内全寿命周期运行成本及碳交易成本最小为目标,对执行季节性碳交易机制的PIES 进行低碳经济调度,分析长时间尺度下季节性储能参与调度的减碳量.搭建IEEE 33节点电网5节点气网7节点热网的 PIES,并基于多场景进行算例分析,验证此调度方法能够实现零碳经济运行,保证系统供能可靠性,为建立零碳园区奠定理论基础.
Low-carbon Economic Dispatch of Park Integrated Energy System Based on Seasonal Carbon Trading Mechanism
In order to effectively improve the rationality of the allocation of carbon emission quotas and avoid the problem of aggravating environmental pollution caused by excessive carbon emissions during the annual settlement,this paper proposes a seasonal carbon trading mechanism based on reward and punishment factors.Low-carbon economic dispatch is carried out with the park integrated energy system(PIES)as the object.First,an integrated energy system(IES)operation framework including the energy layer,carbon flow layer and management layer is constructed,and a dynamic consistency model of supply and demand of electric-gas-heat multi-energy flow is established.Then,the"daily-seasonal-annual"carbon emission characteristics within the system are estimated.It breaks the quota allocation method of the traditional application index method.The grey relational analysis method is used to establish a carbon emission quota allocation model,and a seasonal carbon trading mechanism is established based on the reward and punishment stepped carbon price.Finally,with the goal of minimizing the operating cost and carbon transaction cost in the whole life cycle of the system,the low-carbon economic dispatch is carried out for the PIES purpose of satisfying the seasonal carbon trading quota.The amount of carbon reduction is also analyzed in the process of long-term seasonal energy storage participating in the scheduling.The PIES of IEEE 33 node power grid with 5-node gas grid and 7-node heat grid is built,and an example analysis is carried out based on multiple scenarios to verify that this dispatch method can realize low-carbon economic operation and ensure the reliability of system energy supply.The result lays a theoretical foundation for the establishment of zero-carbon parks.
