Latterly, reduction of power loss in distribution system is the objective of many researches due to its impact on total costs and voltage profiles. It can be handled by optimal restructure of 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 observation of total losses, cost, and saving. Also, the impact of alterable loading is investigated to prove the effectiveness of the suggested IWOA.

通过改进的鲸鱼优化方法优化网络重组

最近，由于配电系统中的功率损耗会影响总成本和电压曲线，因此降低功率损耗是许多研究的目标。可以通过优化径向分布系统（RDS）的结构来解决。本文介绍了一种创新的方法，通过选择受系统操作约束的最佳开关组合来重组RDS，这是改进的鲸鱼优化方法（IWOA）。所提出的方法将对WOA的开发与对差分进化（DE）的探索结合在一起，因此，它提供了一个有希望的候选解决方案。建议的方法已在IEEE 33和69总线RDS上进行了测试。通过观察总损失，成本和节省的模拟结果，可以证明所建议方法与其他知名方法相比的优越性。也，
