Interval arithmetic in current injection power flow analysis
Abstract
This paper incorporates interval arithmetic into current injection method to solve power flow problem under both load and line data uncertainty. In this new methodology, the resulting interval nonlinear system of equations is solved using Krawczyk method. The proposed methodology is implemented in the Matlab environment using the Intlab toolbox. Results are compared with those obtainable by Monte Carlo simulations. IEEE test systems and a South – southeastern Brazilian network are used.
