摘要
针对启发式方法和智能优化方法在求解配电网重构问题时存在难以获得全局最优解、效率较低的问题,以及矿用配电网重构快速性、稳定性的要求,提出了一种改进烟花算法用于求解矿用配电网重构。以配电网的网络损耗最小为目标函数,通过引入自适应系数对爆炸算子和终止策略进行改进,以减少迭代次数,提高算法的搜索效率;同时结合最优烟花微调策略,避免最优烟花爆炸产生大量相同火花,有效提高火花的多样性。实验结果表明,改进烟花算法具有较高的稳定性和可重复性、较快的搜索速度及良好的全局搜索能力,利用该算法对配电网重构问题进行求解后,网络损耗明显降低。
For problems of difficulty in obtaining global optimal solution and low efficiency when heuristic method and intelligent optimization method were used to solve problem of distribution network reconfiguration, and requirements of rapidity and stability of mine-used distribution network reconfiguration,an improved fireworks algorithm was proposed to solve mine-used distribution network reconfiguration.Taking the minimum distribution network loss as objective function,explosion operator and termination strategy are improved by introducing self-adaptive coefficient,so as to reduce iterations and improve search efficiency.Combing with the optimal fireworks fine-tuning strategy,a large number of identical sparks can be avoid during the optimal fireworks explosion,which effectively improves sparks diversity.The experimental results show that the improved fireworks algorithm has higher stability and repeatability,faster search speed and good global search ability,and network loss is obviously reduced by use of the algorithm to solve problem of distribution network reconfiguration.
