LOW-CARBON ECONOMIC DISPATCHING OF REGIONAL INTEGRATEDENERGY SYSTEM WITH CHP-CCS-P2G COUPLING BASED ON CARBONTRADE-GREEN CERTIFICATE JOINT TRADING MECHANISM

提出一种基于碳交易-绿色证书联合交易机制的含热电联产机组、碳捕集和电转气设备联合运行的区域综合能源系统低碳经济调度模型。首先,分析碳交易和绿色证书交易机制的运行原理并构建其模型;同时,研究绿证交易价格变化对可再生能源消纳的影响。然后,在热电联产机组中引入碳捕集和电转气设备,构建热电联产机组、碳捕集和电转气设备联合运行的模型,将碳交易-绿证联合交易机制引入该模型中,并且分析热电联产机组联合运行模式下的电力、热力耦合特性。最后,在算例中通过设置不同的调度场景进行对比分析,结果表明该策略可有效降低碳排放,扩大可再生能源上网空间,使系统的运行更加经济。

The paper proposes a low-carbon economic dispatching model of regional integrated energy system based on carbon tradegreen certificate joint trading mechanism,which includes cogeneration units,carbon capture and power-to-gas equipment combined operation.Firstly,the operating principle of carbon trading and green certificate trading mechanism is analyzed and built its model.At the same time,the influence of green certificate trading price changes on the consumption of renewable energy is studied.Then,carbon capture and power-to-gas equipment are introduced into the cogeneration unit,and a model of joint operation of the cogeneration unit,carbon capture and power-to-gas equipment is constructed.The carbon trade-green certificate joint trading mechanism is introduced into the model,and the coupling characteristics of power and heat under the joint operation mode of the cogeneration unit are analyzed.Finally,in the example,by setting different scheduling scenarios for comparative analysis,the results show that this strategy can effectively reduce carbon emissions,expand the online space for renewable energy,and make the operation of the system more economical.
