Abstract

The invention relates to a method for joint dispatching of combined heat and power units with heat storage and wind power to reduce the emission of sulfur and nitrate. Based on the operation characteristics of wind power and combined heat and power units, comprehensively consider the power generation cost of conventional thermal power units, the operating cost of combined heat and power units, the operation and maintenance cost of wind power, the operating cost of desulfurization and denitrification devices, SO 2 with NO x Charges for sewage discharge, taking into account the relevant constraints of heat balance and power balance, in order to reduce SO 2 , NO x With the goal of improving the amount of emissions and wind power consumption, the joint scheduling of combined heat and power units with heat storage and wind power is implemented, and the scheduling value is determined, which has the advantages of scientific and reasonable, accurate scheduling, and good results.

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...
