LOAD FLOW ANALYSIS IN COMPOSITE SYSTEM RELIABILITY EVALUATION

Abstract

Composite system reliability evaluation is important in the determination of critical outage situations. This involves numerous load-flow studies for different system component outage conditions. The Object of this research project is to examine the existing methods suitable for repeated load-flow analysis in composite system reliability evaluation. A new method and a few modifications have been developed as an extension of the basic Newton's method for load-flow solutions. The main emphasis in the new methods is on the computational time and rate of convergence in comparison with other existing methods for load-flow analysis. The numerical examples illustrate that successful load-flow solutions and considerable computing time can be saved by the proposed methods.
