Abstract :

Power system engineers face difficulty in economic operation of large inter-connected power systems. Economic Load Dispatch (ELD) of large inter-connected power system is complex, constrained and non-lineproblem which require rigorous and complex calculations before taking any decision appropriate to power dispatch. Genetic Algorithms (GA) which are referred to as Evolutionary Algorithms(EA) have been nowadayfrequently used for optimum performance of non-linear and complex systems. This paper proposed to develop an Evolutionary Algorithm which considers Economic Load Dispatch (ELD) problem with security constraintof power systems. The objective is to minimize the non-linear function which is the total fuel cost of thermal generating units, while taking into account the security constraints (power generations, voltages and line flows).
