Constrained Active Power Reschedule Using Immune System Technique for Static Security Enhancement

This paper presents a constrained active power reschedule using immune system for static security enhancement. The study aims to evaluate the static security when a power transmission system is subjected to multi-contingencies. Voltage stability improvement is achieved by performing active power rescheduling in which the optimal value is determined using artificial immune system (AIS). The method was test on IEEE 30-Bus RTS system and results have been compared with Evolutionary Programming (EP) indicating that AIS outperformed EP.
