基于阶梯碳交易的含碳捕集与高耗能负荷的虚拟电厂优化调度OA

To promote low-carbon emissions and enhance the integration of renewable energy,this paper proposes a low-carbon economic dispatch model for virtual power plant(VPP),considering carbon capture and the production characteristics of energy-intensive loads such as electric arc furnace(EAF).First,the operational characteristics of a carbon capture power plant(CCPP)with integrated flexible operation are studied,and its advantages over traditional carbon capture plants are analyzed.Second,the production characteristics of electric arc furnaces in short-process steelmaking enterprises with flue gas treatment systems are examined,and a power model for the electric arc furnace is developed.Then,considering the stepped carbon trading mechanism,a low-carbon economic dispatch model for the virtual power plant is constructed to minimize system comprehensive costs,including operation and maintenance costs,carbon trading costs,equipment depreciation costs,and penalties for wind/solar curtailment.Finally,the model is solved using Matlab with the Gurobi solver.The results show that the proposed model provides better low-carbon economic benefits and improves the new energy consumption rate.
