基于一体化数据平台与改进粒子群算法的配电网重构

以配电SCADA系统的一体化数据库为平台并在离散粒子群算法中嵌入小生境操作，提出了一种改进的配电网重构算法。首先，综合考虑网损、电压损耗、负荷平衡和断路器动作成本等指标确定了适应值评估模型；然后，通过嵌入小生境操作过程对离散粒子群算法进行了改进；结合配电SCADA数据库平台研制了配电网重构系统。最后，对2个配电系统进行了算例研究。结果表明：改进配电网重构算法是可靠的；相对于现有粒子群算法，重构计算速度有一定程度的提高。...

An improved distribution network reconfiguration algorithm is presented by embedding niche operation into discrete PSO based on incorporate database platform. Firstly, the evaluating model of fitness value comprehensively considering line loss, voltage loss, load balance and breaker acting cost is presented; then, the discrete PSO is improved by embedding niche operation process; further, the distribution reconfiguration system is developed based on distribution SCADA database platform. Lastly, two distribution systems are studied. The results prove that the improved discrete PSO is reliable while the calculating process is speeded.
