Dynamic simulation of energy flow based on input and output models of energy network nodes

Establishing the input and output dynamic model of the energy flow network nodes is the key to understand the energy saving and consumption reduction stage and the coordinated optimization of multi-energy medium from both the systematic and global perspective. Based on the energy flow network structure and the metallurgical process engineering theory, the consumption recovery model of the main process production unit nodes and the production consumption model of the energy unit nodes in the energy flow network are studied. Based on the actual data of an iron and steel enterprise ,the input and output of energy flow network nodes are simulated. The analysis results show that the error of the established energy flow network nodes simulation model is small and can effectively simulate the actual energy allocation of iron and steel enterprises. The research has a guiding significance for the planning and scheduling of enterprises under different working conditions.
