Economic Dispatching of Integrated Heat and Electric System Based on Feasible Region of District Heating System
摘要
Abstract
In this paper,the economic dispatching of integrated heat and electric system(IHES)based on feasible region of district heating system(DHS)is studied to achieve fast and accurate calculation of economic dispatching.Firstly,the basic model of IHES is set up to describe the multi-energy flow distribution,including the power system model based on an improved DC model,the dynamic DHS model of system based on partial differential equations(PDE)and the feasible region-based coupling equipment model.Then,the PDE-based DHS model is transformed in-to explicit algebraic equations by a fully analytical method(FAM),and the feasible region model of the DHS is de-rived through network equivalence.The dimensionality reduction of the dynamic DHS model is consequently achieved while the accuracy is maintained.On this basis,the safe operation constraints of the IHES is considered fur-ther and,combined with the feasible region model,the economic dispatching model of the IHES is set up so to achieve minimum operational cost.Finally,the advantages of efficiency and accuracy of the DHS based on the FAM in the economic dispatching of integrated and electric system is verified by comparison of the simulation examples.关键词
