Abstract


This paper presents a methodology to solve load flow problems in which the load data are uncertain due to measurement errors. In order to deal with those uncertainties we apply techniques of Interval Mathematics. The algorithm uses the Interval Newton’s method to solve the nonlinear system of equations generated by the problem. The implementation was performed in theMatlabr environment using the Intlab toolbox. In order to assess the performance of the proposed algorithm, the method was applied to hypothetical electric systems. In this paper, we present results for a three-bus network.
