Cuckoo Search Algorithm in Loss Minimization via Capacitor Placement in Distribution System

Abstract

Improper placement of capacitor as one of the compensating devices will lead to under-compensation or over-compensation which may lead to possible monetary losses. Thus optimization process has become a priori to address this problem. This paper presents cuckoo search algorithm in loss minimization via capacitor placement in distribution system. Implementation of sensitivity analysis for location identification; followed by optimal sizing determination via cuckoo search is a remarkable effort for the compensating scheme. Validation on a reliability test model, namely the IEEE 33-bus radial distribution system has indicated promising results. With the development of optimization engine, an attempt to assess its feasibility can be done through the implementation on larger test system. This is demonstrated by the simulation results, which revealed that cuckoo is feasible in ensuring loss has been minimized while maintaining voltage level within the acceptable range
