Cuckoo search algorithm based optimal reactive power dispatch

Optimal reactive power dispatch (ORPD) is real power loss minimization aspect of power system which has gained several attentions from the researchers. Here by ORPD, real power loss of the network is attempted to be minimized and bus voltages are kept within stable voltage margin. ORPD is generally solved by controlling generator bus voltages, transformer tap settings and by placing shunt Var compensator in few buses. The optimal determination of the said variables are organized in this paper by applying a newly proposed nature inspired meta-heuristics technique i.e., Cuckoo search algorithm (CSA). As a test case IEEE 14-bus system is considered. The CSA based obtained results are compared with other reported evolutionary technique based results. The comparative study shows the effectiveness of the applied Cuckoo Search Algorithm technique.
