Abstract

In the present work static and variable shunt capacitors are sized and placed in the given radial distribution system. Cuckoo Search Algorithm (CSA), used as an optimization algorithm for both placing and sizing. Placement of capacitors improves the voltage profile of the system. Static Capacitor (SC) is placed for 50 percent load condition and Variable Capacitor (VC) is placed for varying load condition. The SC and VC are placed and validated for IEEE-33, bus test systems and on 22, 29 bus practical system.
