Optimization Methodology for Carbon Capture Reformation Schemes in Thermal Power Plants Considering the Power Flexible Ramping Demand
摘要
Abstract
[Objective]In the context of high-percentage renewable energy integration,to satisfy the system flexibility and low-carbon demand,we propose an optimization method for the carbon capture reformation of thermal power plants considering the flexible power ramping demand.[Methods]First,a calculation model for the power system flexibility demand is established to address the ramping demand surge caused by large-scale wind and photovoltaic power integration.Second,a flexible operation model of thermal power units considering carbon capture reformation is established,and the flexible ramping supply capacity is quantified.Subsequently,considering the uncertainty of the load and renewable energy,a flexible ramping demand constraint and a fuzzy opportunity-constrained model are introduced to establish a carbon capture reformation planning model for thermal power plants.This model jointly solves the carbon capture reformation planning and operation optimization problems of thermal power units to obtain an optimal carbon capture reformation solution.Finally,the effectiveness of the planning model is verified using examples,and the impacts of different unit carbon penalties,renewable energy integration ratios,and confidence levels on the carbon capture reformation results are analyzed.[Results]Simulation results showed that after the optimal carbon capture reformation of thermal power plants,the carbon emissions of the power system were significantly reduced,the renewable energy curtailment rate was significantly reduced,and the total operating cost of the system was reduced by 9.44%.[Conclusions]Through optimal carbon capture reformation of thermal power plants,the output downward regulation space and ramping capability of thermal power plants can be improved,which can promote the accommodation of renewable energy while reducing the carbon emissions of the power system,thus enhancing the economic efficiency of system operation.关键词
