摘要: 垃圾焚烧电厂的烟气处理能耗在总出力中占较大比例,其上网出力受到发电环节与烟气处理环节耦合关系的限制。通过加装储气装置,调控烟气处理时间,实现两者关系解耦,提高垃圾焚烧电厂在担任风电大规模并网配合电源时出力调整的灵活性。将风电厂、垃圾焚烧电厂、加装储气装置后的烟气处理系统聚合为虚拟电厂,以整体净收益最大化为目标,建立包含储气装置烟气处理系统子模型的日前-实时双阶段优化调度模型。以日前调度结果作为申报出力,根据风电实际出力与预测出力偏差,调整储气装置的烟气量,实时修正垃圾焚烧电厂的净出力,以跟随风电变化。仿真结果验证了所建模型的合理性,在实际应用中具有显著经济及社会价值。

Abstract: The energy consumption for the flue gas treatment in the waste incineration power plant accounts for a large proportion of the plant's total power output, and its on-grid output is constrained by the coupling relationship between the power generation and the flue gas treatment. The relationship between the above two factors is decoupled through the installation of gas storage devices and controlling of the flue gas treatment time, so as to improve the flexibility of the waste incineration power plant in power output adjustment for grid-connection of large-scale wind power. The wind power plant, waste incineration power plant and the flue gas treatment system added with gas storage devices are integrated into a virtual power plant. Aiming at maximizing the overall net benefit, a day-ahead-real time two-stage optimal dispatching model is established, which includes the sub-model of flue gas treatment system with gas storage device. By using the day-ahead dispatching results as the report output, the amount of flue gas in the gas storage device is adjusted according to the deviation of actual and forecasted wind power output, and the net output of the waste incineration power plant is corrected in real time in order to follow the changes of wind power. Simulation results have verified the rationality of the proposed model, and the model has significant economic and social value in practical application.

Key words: flue gas storage, waste incineration power plant, virtual power plant, two-stage optimal dispatch
