基于风电-碳捕集虚拟电厂的环保经济调度

Environmental Economic Dispatch Based on Virtual Power Plant with Carbon Capture Unit and Wind Power

  • 摘要: 风电间歇性和波动性强,难以被直接调度。储液式碳捕集机组能快速改变捕集系统运行状态,将其与风电聚合为虚拟电厂整体参与调度。以各时段内该虚拟电厂在电力市场与碳市场中的净收益最大为目标,构建包含溶液储量关系子模型的日前-实时双阶段环保经济调度模型。以日前调度结果作为申报出力,根据风电出力偏差,实时修正碳捕集机组净输出功率以跟随风电变化。仿真结果验证了模型的合理性。虚拟电厂联合运行模式可协调优化内部各单元的出力安排与净碳排放水平,使风电成为可调度资源;相较于独立运行模式,能获得更显著的碳减排效益和更高的经济效益。

     

    Abstract: Wind power is difficult to be direct dispatched because of its strong intermittence and fluctuation. The solvent-storaged carbon capture unit can change the operating status of the capture system quickly, and its integration with wind turbine participates in grid dispatching as a virtual power plant (VPP). Taking the maximum net income of the VPP in the electricity market and carbon trading market as the objective, the day-ahead and real-time two-stage environmental economic dispatch model which contains a sub-model of describing relationship between volumes of stored solvents is constructed. The day-ahead scheduling results are taken as the declaratory output of the VPP. Then the net power output of the carbon capture unit is amended real-time according to the wind power deviation. In the end, simulation results verify the rationality of the proposed model. In addition, the joint operation mode of the VPPs show that the VPPs can optimally coordinate the power output arrangement and net carbon emission level of internal units to make wind power become a scheduling resource. Compared with the independent operation mode, more obvious carbon emission reduction benefit and higher economic benefit can both be obtained.
