摘要：

A probabilistic energy flow calculation method for integrated energy systems based on the radial basis function stochastic response surface method was proposed. First, the node temperature equation of heat network was derived, and the limitations of the chaotic polynomial stochastic response surface method and sparse chaotic polynomial stochastic response surface method in calculating the node temperatures of heat network were verified and analyzed. Then, the radial basis function stochastic response surface model was established and extended by using linear polynomials, and its way of configuration points was improved. Based on this, the radial basis function stochastic response surface method applicable to the probabilistic energy flow calculation of integrated energy systems was proposed and a detailed computational procedure was given. Finally, the validity and performance of the proposed method were verified and evaluated by standard and practical cases. The results show that the proposed method has good computational accuracy and efficiency in calculating the probabilistic energy flow of integrated energy systems with heat network. ©2022 Chin.Soc.for Elec.Eng. 8075.
