Probabilistic load flow considering network outages

Many techniques have been proposed to solve the load flow problem probabilistically. The great majority have only accounted for load and generation data uncertainties, and therefore, the network configuration has been considered fixed. So far, the effects of the configuration uncertainties due to the probabilistic nature of the network have not been deeply analysed. The paper presents a new method for obtaining a probabilistic load flow solution when network outages are modelled as a random variable. The proposed technique is applied to a typical power system and the results discussed.
