Description

technical field

[0001] The invention relates to the technical field of energy saving, in particular to a thermal power plant plant-level load optimization distribution method based on multiple constraint rules. Background technique

[0002] At present, thermal power generating units account for more than 70% of the country's total installed capacity and consume a huge amount of non-renewable coal resources. Therefore, in-depth research on energy saving and consumption reduction of thermal power generating units is of great significance to the sustainable development of the national economy. Plant-level load optimization distribution is an important measure for energy saving and consumption reduction. By optimizing the load distribution of the units in the whole plant, the cost of comprehensive power supply is minimized under the condition of meeting the load requirements of the power grid and the output constraints of the units. In addition, reasonable optimal load distribu...
