Probabilistic three-phase load flow for unbalanced electrical systems with wind farms

In this paper, a three phase probabilistic load flow for transmission system based on point estimation method along with three phase unbalanced induction generator model for the wind farm has been proposed. The proposed method is tested on a IEEE-118 bus three phase system and accuracy of the results have been validated by comparing the results with those obtained by Monte Carlo simulation studies. The effect of variation of standard deviation of the connected loads on the system and effect on the voltage profile has also been studied. (C) 2016 Elsevier Ltd. All rights reserved.
