Optimal electric distribution network configuration using adaptive sunflower optimization

Thuan Thanh Nguyen


Network reconfiguration is one of effective approaches for power loss reduction in the distribution system. This paper presents a method of network reconfiguration using adaptive sunflower optimization (ASFO) to minimize power loss of the distribution system. ASFO is developed based on the original sunflower optimization (SFO) that is inspired from moving of sunflower to the sun. In ASFO, the mechanisms including pollination, survival and mortality mechanisms have been adjusted compared to the original SFO to fit with the network reconfiguration problem. The numerical results on the 14-nodes and 33-nodes systems have shown that ESFO outperforms to SFO for finding the optimal network configuration with greater success rate and better obtained solution quality. The comparison results with other methods in literature also show that ASFO have better performance than other methods in term of optimal network configuration. As a result, ASFO is an effective method for the network reconfiguration.
