Newton-raphson load flow with consideration of the fuzzy load and in the presence of the distributed generations in distribution network

In this paper, the fuzzy technique is presented for modeling load points uncertainty in distribution systems load flow problem in the presence of distributed generations. A fuzzy set theory is the proper way to model inaccurate data and information that are associated with uncertainty. In this paper, the combinations of the fuzzy set of models and techniques to calculate the electrical distribution networks have been described. In addition, the theories associated with fuzzy numbers are simplified in suitable conditions for practical applications. Using fuzzy method for the fuzzy load flow is presented when the load nodes are displayed in the form of fuzzy numbers. This method is carried out on 33-buses network in MATLAB7 environment and the results have been studied.
