The reconfiguration process for the electrical radial distribution system is to find a
radial operating framework that minimizes power losses of electric distribution networks. It is a
combinatorial and complex procedure to determine the optimum radial configuration of the
distribution system by frequently varying the operating status of network switches with keeping the network operating constraints. Therefore, this paper proposes the Harris hawks optimization
(HHO) to find the optimal combination of switches that results in a radial configuration with
minimum system power loss. The main revelation of this algorithm is the cooperative behavior and chasing manner of Harris' hawks in nature. In HHO operation, many hawks attack their victims
cooperatively from several paths trying to surprise it. Harris hawks can detect a variety range of
chasing patterns based on the dynamic nature of circumstances and escaping patterns of the victim.
The validation of suggested HHO method is tested on the 33 IEEE bus distribution network. In
addition, the obtained results proved the accuracy and efficiency of the suggested algorithm by
comparing with other existing optimization algorithms.
