A new approach to monitor line overloading in deregulated power system using electricity tracing

Abstract

In this paper, the technique of electricity tracing has been widened into monitoring line overloading of deregulated power system. Recently, the study on power system stability can only determine the stressed transmission lines but no attempt to trace who become the contributors (generators or loads) for the system's violation. By means of electricity tracing, the objective to trace the major contributor can be achieved. Thus, this paper proposes the application of electricity tracing through hybrid algorithm: The Ant Colony Pollinated-Flower Algorithm (ACPFA) for tracing the stress contributors. The experiment on IEEE 14-bus system together with comparative studies has validated the performance of the proposed method and algorithm. The results proved a promising capability for electricity tracing's application in monitoring line overloading of a deregulated power system.
