Optimal Network Reconfiguration via Improved Whale Optimization Approach

Latterly, reduction of power loss in the distribution system is the objective of many researches due to its impact on total costs and voltage profiles. It can be handled by an optimal restructure of the Radial Distribution System (RDS). This article introduces an innovative approach to restructure of RDS by electing the optimal switches combination subject to the system operating constraints, which is Improved Whale Optimization Approach (IWOA). The suggested approach combines exploitation of WOA with exploration of Differential Evolution (DE), and thus it supplies a promising candidate solution. The suggested approach is tested on IEEE 33 and 69 bus RDS. The superiority of the suggested approach compared with other well-known approaches is verified through simulation results by examining total losses, cost and saving. Also, the impact of alterable loading is investigated to prove the effectiveness of the suggested IWOA.
