PROBABILISTIC LOAD FLOW IN DISTRIBUTION-SYSTEMS CONTAINING DISPERSED WIND POWER-GENERATION

In this paper a probabilistic model for the active power produced and the reactive power absorbed by Wind Turbines (WTs) equipped with induction generators is developed which takes into account the probabilistic nature of short-term wind velocity forecasts. The model is incorporated in a radial distribution load flow program which allows probabilistic modeling of loads at the MV/LV substation level and of voltage regulator effects at the beginning of the MV distribution feeder. Using this program probabilistic short- and medium-term predictions of the power flows at the various sections of the feeder and of voltage profiles at all nodes of the network are obtained.
