A method for synergistic optimization of material flow and energy flow and carbon emission management in steel enterprises

Abstract

This invention discloses a method for the coordinated optimization of material flow and energy flow and carbon emission management in steel enterprises. The method includes the following steps: constructing a network model of material and energy flow in steel enterprises based on graph theory; introducing a dynamic adjacency matrix, with matrix elements quantitatively representing inter-process material / energy flow, energy efficiency parameters, and time delay characteristics; constructing an energy flow balance equation based on the adjacency matrix, aiming to minimize total energy consumption and maximize residual energy recovery rate; using an improved genetic algorithm to solve for the optimal scheduling scheme, dynamically matching production plans with energy supply; constructing a dynamic accounting model embedding process-level carbon emission factors, automatically generating carbon emission reports through real-time collection of EMS data; and providing carbon reduction strategies in conjunction with carbon quota prediction. This method can achieve accurate description and quantitative characterization of material and energy flow in steel enterprises, optimize energy scheduling, accurately calculate carbon emissions, and realize integrated management of energy and carbon emissions.
