A fast probabilistic energy flow (PEF) analysis method is proposed for integrated distribution power and heating system (IPHS) operations. The proposed solution will overcome the low efficiency of the Monte Carlo Simulation (MCS) method for calculating the probabilistic energy flows (PEFs) iteratively, which will require an exhaustive set of energy flow calculations for a large number of samples. First, we use the multi-dimensional holomorphic embedding method (MDHEM) to derive the analytical energy flow expressions, so that the solutions for massive scenarios can be obtained by merely substituting the boundary conditions into expressions. Second, a PEF analysis model is established based on the analytical method for evaluating the impact of uncertainties on IPHSs, and accelerating the efficiency of traditional MCS methods significantly. Case studies presented in the paper show the effectiveness of the proposed method for calculating the PEFs in IPHS operations.
