Description

technical field [0001] The invention relates to a method and system for simulating and predicting load scheduling and distribution of a multi-heat source heating system based on urban atmospheric diffusion process, belonging to the field of multi-heat source heating load scheduling. Background technique [0002] Some cities in my country have always assumed the important responsibility of hosting various large-scale sports events, commemorative activities, and forums and summits. The air quality assurance measures during major events have always attracted the attention of researchers in many fields. Such measures are characterized by phased, temporary, comprehensive and intensive measures. Through high-intensity pollution reduction measures, the ambient air quality can be significantly and effectively improved, and the smooth development and progress of activities and meetings can be guaranteed. [0003] At the same time, with the increasing pressure on the urban environmen...

Problems solved by technology

However, the current air quality assurance measures during major events only use meteorological forecasts to analyze pollution characteristics and pollution laws, and "one size fits all" shut down all polluting heating sources in key protection areas

Failure to consider the possibility of heat source pollution in other areas spreading to the key protection areas under the action of meteorology and the disassembly of the heat network and the constraints of transmission and distribution capacity will easily lead to insufficient heat supply after the heat source is turned off in the key protection areas
