Abstract

The invention relates to a heat accumulation-contained combined heat and power generation unit for reducing sulfur-nitrate emission, and a wind and power combined dispatching method. The method of theinvention is characterized by comprising the steps of analyzing the operation characteristics of the combined heat and power generation unit and the operation characteristics of the wind and power operation; determining the combined dispatching value of the combined heat and power generation unit and the wind and power operation; based on the operation characteristics of the wind and power operation and the combined heat and power generation unit, and comprehensively considering the power generation cost of a conventional thermal power generating set, the operation cost of the combined heat and power generation unit, the maintenance cost of the wind and power operation, the operation cost of a desulfurization and denitrification device and the pollution discharge collection cost of SO2 and NOx. According to the method, the relevant constraints of thermodynamic balance and electric power balance are given consideration to, and the emission of SO2 and NOx is reduced. The improvement ofthe wind and power generation amount is adopted as a target, and the combined scheduling of the heat accumulation-contained combined heat and power generation unit and the wind and power operation isconducted. Meanwhile, the scheduling value is determined. The method is scientific and reasonable, accurate in scheduling and good in effect.

Description

[0001] The invention relates to the technical field of joint dispatching of heat and power cogeneration units and wind power, and relates to a method for joint dispatching of heat and power cogeneration units with heat storage and wind power that reduces sulfur and nitrate emissions. Background technique [0002] In recent years, air pollution has intensified, extreme weather has occurred frequently, and SO 2 , NO x is an important cause of air pollution. For Northeast my country, North China and Northwest China, referred to as the "Three Norths" for short, the combined heat and power (CHP) operation mode of "heating power" during the winter heating period further limits the grid connection of new energy power generation. The consumption has led to the phenomenon of large-scale abandonment of wind and light, which has exacerbated the deterioration of the environment. With the enhancement of people's awareness of environmental protection and the promulgation of relevant nation...
