摘要/Abstract

摘要： 热电联产机组配置电锅炉进行热电解耦以促进风电等新能源的并网。为了确定热电联产机组参与电网调峰时电锅炉的最佳配置容量，引入特征日的概念，对电锅炉运行时的约束进行说明，分别以机组调峰增量和经济净现值为目标函数，建立电锅炉最佳容量的计算模型。结果表明，对于330 MW机组，当不考虑投资成本时，电锅炉的供热功率达到52 MW时，机组可以获得最大的调峰增量，此时，电锅炉的电加热功率为178.28 MW；若考虑投资成本，当电锅炉的供热功率达到49 MW时，即电锅炉的电加热功率为168 MW时，可以得到最大的经济净现值。

Abstract: The cogeneration unit is equipped with an electric boiler for thermal electro-coupling to promote the integration of new energy such as wind power. To determine the optimal capacity configuration of the medium-electric boiler in the thermal power plant, the concept of the feature day is introduced, and the constraints during the boiler operation are elaborated in this paper. Then a mathematical model is established by setting peaking increment and economic net present value of the unit as the objective functions respectively. The results show that for the 330 MW unit, when the heating supply of the electric boiler reaches 52 MW, the maximum peak-increasing increment can be obtained if the investment cost is not considered. The electric heating power of the electric boiler is 178.28 MW by then. While in the case of the investment cost taken into account, with the heating power of the electric boiler reaching 49 MW, the electric heating power of the electric boiler is 168 MW and the maximum economic net present value is achieved.

Key words: CHP unit, wind and heat conflict, electric boiler, peak load increment, economic net present value, optimal capacity
