LOW-CARBON ECONOMIC DISPATCHING OF REGIONAL INTEGRATED ENERGY SYSTEM WITH CHP-CCS-P2G COUPLING BASED ON CARBON TRADE-GREEN CERTIFICATE JOINT TRADING MECHANISM
The paper proposes a low-carbon economic dispatching model of regional integrated energy system based on carbon trade-green 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.
