This paper studies the supply and demand optimization method of urban energy systems. Firstly,taking the minimum total cost of energy system as the target,we establish the supply and demand optimization model of urban energy system with considering multiclass energy planning constraints. Secondly,we introduce the improved multispecies hybrid evolutionary algorithm to determine the optimal process of the model. Finally,we use the related results of the terminal energy consumption forecast model as demand constraints,and apply the model to the example analysis of T city. The results showthat the optimal energy supply results during the future planning period obtained in the model can meet the requirements of urban energy relative policy documents,which will guide the energy supply of T city to clean and sustainable development direction.
