Abstract

The network reconfiguration can aid in loss reduction in distribution systems. A neoteric optimization method, Sunflower Optimizer (SFO), is suggested for addressing the reconfiguration of power distribution networks case. The main problem is to determine the network's optimal topology, which satisfies the objective function by considering the problem constraints. The fitness function is formulated to achieve the maximum percentage of active power loss decrease. To obtain the load flow solution, an efficient approach is applied called Backward/forward sweep. Besides, an improved graph theory is developed to address the configuration variations problem. The suggested optimization approach is executed on three power distribution networks: IEEE 33, 69, and 119 bus networks. The efficiency of the suggested SFO is verified by evaluating its operational characteristics. The obtained test results show that the percentage of active power loss reduction is maximized to 31%, 56%, and 33% for the IEEE 33, 69, and 119 bus networks, respectively. Finally, the introduced SFO approach's superiority is also confirmed by measuring its outcomes with other approaches..
