Reactive power management through dispatch analysis using evolutionary algorithms

Abstract

Sufficient reactive power requires to maintain system terminal voltages. Reactive power is an important ancillary service requires to be provided locally. Reactive power management involves two main important parts economical reactive power procurement and economical reactive power dispatch which also satisfy technical constraints. Main centering of this work is to dispatch reactive power by considering it as important optimization problem of power system. ORPD is solved as single objective function and multi objective function. Two main objective functions (1) Minimization of real power loss and (2) Diminution of L-index are considered and problem is tested for different IEEE bus systems and results were compared for SPEA and NSGA-II techniques.
