Load flow analysis uncertainty treatment via fuzzy arithmetic

Ayub, Zatul Akmar (2009) Load flow analysis uncertainty treatment via fuzzy arithmetic. Masters thesis, Universiti Teknologi Malaysia, Faculty of Electrical Engineering.



Load flow analysis uncertainty treatment via fuzzy arithmetic is a method which applying fuzzy arithmetic to model vagueness, ambiguity and uncertainties in power system analysis. In this study, trapezoidal method and transformation method have been employed to solve the uncertainties in load flow analysis where LR (left-right) fuzzy arithmetic have been applied to model the uncertainties and another method is by composing fuzzy numbers into intervals by using transformation method. The fuzzy load flow has been performed to get the ouput results. The simulation study is conducted for IEEE 5-bus test system and IEEE 9-bus test system using both methods. The output voltage of the fuzzy load flow has been plotted against their membership function to validate the result in terms of fuzzy distribution and to compare which method is more efficient as solution for load flow uncertainties treatment.
