AB  - Recently, minimization of power losses in
distribution system is the objective of many researches
due to its effect on voltage profiles and total cost. This
problem can be handled by optimal reconfiguration of
Radial Distribution System (RDS). Improved Whale
Optimization Algorithm IWOA which is inspired from
social behavior of humpback whales is proposed to
restructure the RDS by selecting the optimal switches
combination subject to the system operating constraints.
The proposed algorithm combines exploitation of WOA
with exploration of Differential Evolution (DE) and
therefore it provides a promising candidate solution. The
proposed algorithm is tested on IEEE 33 and 69 bus RDS.
The effectiveness of the proposed method comparing with
other well-known optimization techniques is proved
through simulation results by examining total losses, cost
and saving. Also, the effect of variable loading is
considered to ensure the superiority of the proposed
IWOA.
