Finding Radial Network Configuration of Distribution System Based on Modified Symbiotic Organisms Search

Network reconfiguration (NR) is one of the most effective methods to reduce line power loss in distribution system, which causes higher losses than other parts system. This paper proposes a modified symbiotic organisms search (MSOS) algorithm solve NR problem. For purpose enhancing effectiveness MSOS, mutualism and parasitism strategies original (SOS) have been create better new solutions. In strategy, so-far best solution updated immediately as soon solutions are created. update only implemented for first half control variables, whereas another still remains unchanged. The comparison results between MSOS SOS on twenty-five benchmark functions different scales test systems with 14, 33, 69, 119 nodes show that improvement level over significant success rates quality gained Similarly, also reaches literature. Consequently, can be favorable method determining appropriate configurations systems.
