A VOLTAGE‐BASED AUTOMATIC CONTINGENCY SELECTION ALGORITHM VIA A LINEARIZATION METHOD

This paper describes a fast method for determining voltage changes due to line outages. Its extension to the identification of system islands as well as a formulation of a voltage‐based contingency selection algorithm is explained. The performance of the method is evaluated using the 6‐bus Saskatchenan Power Corporation, IEEE 14‐bus and 23‐bus Nigerian Power Systems networks neglecting the effect of voltage controls.
