Description

technical field [0001] The invention relates to the technical field of thermoelectric system dispatching in iron and steel enterprises, in particular to a method, system and computer-readable storage medium for dispatching thermoelectric systems in iron and steel enterprises. Background technique [0002] As one of the basic pillar industries of my country's national economy, the iron and steel industry is the foundation and key to the development of other industries. However, at the same time, iron and steel enterprises are high-energy-consuming and resource-based industries. It also causes a waste of resources. The benefits of iron and steel enterprises are affected by the efficiency of energy utilization. In the production process of steelmaking and ironmaking, a large amount of by-product gas is produced, including coke oven gas, blast furnace gas, and converter gas. The by-product gas is an important secondary energy source for enterprises, accounting for about one-thir...

Problems solved by technology

[0004] The traditional scheduling method is the most effective method in the scheduling problem, and can obtain the optimal solution, but for complex large-scale optimization problems, it is often limited by the problem scale, and the solution time increases with the increase of the number of variables.

However, the characteristics of the solution of the intelligent scheduling method are relatively poor. The shorter the solution time and the tighter the constraints, the less likely it is to find a good solution. When the process structure changes, the scalability is poor.
