摘　　要：配电网络的复杂性和不确定性使得传统的优化方法难以有效降低线路损耗。现有算法在快速收敛和全局搜索之间难以平衡。因此,本研究选择了蜻蜓算法,该算法具有多样性强、快速收敛和全局搜索能力突出的特点,因此,将其应用于配电网络的线路损耗优化问题中以解决配电网络线损问题。通过调整抽头变压器和分布式电源的功率因数,并灵活配置关键开关,基于蜻蜓算法逐步优化了配电网络。实验结果表明,在IEEE 14节点网络中,采用蜻蜓算法后,线路损耗比初始状态减少了8.43%;传统算法在热季与寒季分别比蜻蜓算法多出了3.256%与3.75%的线路损耗,因此,相较于传统的遗传算法,蜻蜓算法不仅更快地找到了最优解,而且避免了陷入局部最优解的困境,取得了更为可观的优化效果。因此,本研究通过提出并成功应用蜻蜓算法,为配电网络的线路损耗优化问题提供了一种创新性解决思路,同时,也提高了系统的效率和可持续性。The complexity and uncertainty of distribution networks make it challenging to effectively reduce line losses using traditional optimization methods.Existing algorithms struggle to balance fast convergence with global search capabilities.Consequently,this study adopts the Dragonfly Algorithm,known for its strong diversity,rapid convergence,and exceptional global search capabilities,to address distribution network losses.By adjusting the power factors of tap transformers and distributed power sources and configuring critical switches flexibly,the distribution network was progressively optimized based on the Dragonfly Algorithm.The experimental results indicate that in the IEEE 14-node network,employing the Dragonfly Algorithm led to an 8.43%reduction in line losses compared to the initial state.Traditional algorithms resulted in higher line losses of 3.256%and 3.75%during the hot and cold seasons,respectively,in comparison to the Dragonfly Algorithm.Therefore,relative to the conventional Genetic Algorithm,the Dragonfly Algorithm not only discovers the optimal solution more rapidly but also avoids the pitfalls of local optima,achieving significantly improved optimization outcomes.This study,by proposing and successfully applying the Dragonfly Algorithm,presents an innovative approach to optimizing line losses in distribution networks,simultaneously enhancing system efficiency and sustainability.
