Research on day-ahead optimal scheduling of integrated energy system in industrial parks based on flexible load characteristics
Studying the adjustable characteristics of industrial flexible loads is an effective way to enhance the dynamic regulation ability of power grids.There are a large number of industrial load resources with potential for regulation on the user side of industrial parks.In response to this characteristic,a comprehensive energy system mathematical model of industrial parks was constructed based on energy hubs,including distributed power generation systems,energy storage power plants,gas turbines,gas boilers,flexible loads,etc.,and a method for optimizing and scheduling the energy system of industrial parks in the future considering the flexible characteristics of loads was proposed.Firstly,the translatable,transferable,and interruptible load characteristics of flexible loads such as electrolytic aluminum on the system demand response side was considered.Secondly,taking into account production and operation factors,a system optimiza-tion scheduling model was established with the objective function of minimizing the sum of energy purchase cost,compensation cost,and operation and maintenance cost.Finally,based on Matlab software and the Cplex solver,the effectiveness of the proposed model was ver-ified through comparative analysis of three different typical scenarios.The example analysis shows that considering the coupling optimi-zation of industrial flexible electricity and heat loads,the cost is the lowest,which is 6.6％lower than the cost without the participation of flexible loads.Research and analysis have shown that optimizing the allocation of industrial flexible load resources can promote the consumption of new energy,reduce the pressure on industrial electricity consumption,and improve the economic efficiency of industrial park system operation.
