This paper presents a general algorithm to determine the affects of uncertainty in bus load and generation on the output of conventional power flow analysis. The use of statistical moments is presented and developed as a means for representing the stochastic process. Under this concept, statistical moments are used to describe the probability density functions, allowing virtually any type of distribution, and eliminating any requirements of statistical independence. The power flow equations are reqpresented as a quadratic function evaluated at the expected values of input load. Conditional expected values are computed as well as probabilities to indicate overload severity. The results are compared with Monte Carlo simulation.
