Integrated energy system is an important development trend of energy system in the future.As an important form of integrated energy system in local areas,regional integrated energy system has the complex characteristics of multi-energy supply.Therefore,this paper studied the planning model of regional integrated energy supply system.Firstly,the planning index system of regional integrated energy supply system was constructed.Secondly,based on the planning index system,considering the multiple constraints of power grid and heat grid,a regional energy supply system planning model was established to realize the minimum comprehensive cost of investment,operation,economy and environment.Finally,the example shows that the proposed planning model has better economic performance than the traditional planning scheme.
