Abstract
This study aims to assimilate distributed generation (DG) unit using a novel hybrid technique to improve the efficiency of
electric power distribution networks by minimizing the real power losses (RPL) and enhancing the bus voltages (BV). A
hybrid technique has been implemented by combining the features of nature-inspired algorithms namely hunter-prey
optimizer (HPO) and ant lion optimizer (ALO) algorithms. The exploitation characteristic of ALO and exploration
characteristic of HPO is utilized to optimize single DG in radial distribution power network (DPN). The efficacy of
the suggested hybrid optimization technique is validated using MATLAB/Simulink software tool. The proposed hybrid
technique was executed to optimize type I and type III DG in a balanced IEEE 69-bus radial DPN. The optimized type
I and type III DG placement minimized the real power losses of a test system to 71.23 kW and 20.38 kW, respectively.
Additionally, the least bus voltage of the test system improved to 0.9776p.u and 0.9843p.u following type I and type III DG
allocation. The optimized allocation of type I DG and type III DG has resulted in 68.34% and 90.94% power loss reduction,
respectively and enhanced the minimum bus voltage of the test system by 7.5% and 8.3%, respectively. The efficacy
of the proposed hybrid methodology was investigated by relating its simulation outcome with other optimization
methodologies present in the literature. The comparative results revealed that the proposed hybrid optimization
technique provided better RPL minimization at improved BV than the compared optimization techniques.
