Aim: This work proposes a comparative analysis of two algorithms named a novel Cuckoo Search Algorithm (CSA) and a Bat Algorithm (BA) for enhancing the bus voltage in the Distribution Network by optimal allocation of a shunt capacitor. Materials and Methods: Novel Cuckoo Search Algorithm and Bat Algorithm are utilized for optimal location and sizing of shunt capacitors in the radial distribution system. The sample size is calculated using Gpower for two groups and there are 14 samples used in this work. The G power is taken as 0.8. Results: Based on the results obtained CSA produces better results than BA in terms of bus voltage enhancement. The significant value obtained is 0.001 (p<0.05) which is statically significant. Conclusion: CSA-based optimization method provides significantly better bus voltage enhancement (0.9507 p.u) than BA-based method (0.9469 p.u).
