Power system reliability can be evaluated through probability power flow calculations. Probability power flow is a method used to assess the probability distribution of power systems under specific conditions. Beyond traditional probabilistic analysis methods, this implementation utilizes the cumulant method and Gram-Charlier series expansion for analysis. The algorithm employs cumulants to characterize probability distributions and applies Gram-Charlier series to approximate the distribution function, offering superior convergence properties and more accurate probability distribution computations. The program implementation involves key functions for cumulant calculation, series expansion coefficients derivation, and distribution reconstruction. Therefore, systems developed using the cumulant method and Gram-Charlier series expansion can provide more reliable assessment of power system reliability with efficient computational performance.
