Reconfiguration of a Radial Distribution System using the Harris Hawks Optimization Algorithm

Recently, reducing power loss in distribution systems has become a key focus of various studies due to its influence on gross costs and voltage gradients. One solution is the optimal reconfiguration of the Radial Distribution System (RDS). This study presents an inventive tactic to reconfigure RDS by selecting the best switch combinations while considering system operating constraints, using the Harris Hawks Approach (HHA) which is a nature-inspired optimization paradigm. The primary inspiration for HHA comes from the cooperative behavior and hunting technique of Harris’ hawks in the wild, regarded as the “surprise pounce”. In this clever strategy, distinct hawks work together in order to pounce on their prey from multiple pathways, aiming to catch them by surprise. Harris' hawks are capable of identifying various chasing patterns, influenced by the dynamic nature of the situation and the escape tactics of the prey. The mentioned approach is examined on IEEE 33 node RDS. The effectiveness of this approach, in comparison to other established methods, is demonstrated via simulation results that assess total losses, costs, and savings. Additionally, the statistical analysis is conducted to validate the potency of the advised HHA.
