With the development of automation in smart grids, network reconfiguration is becoming a feasible approach for improving the operation of distribution systems. A novel reconfiguration strategy was presented to get the optimal configuration of improving economy of the system, and then identifying the important nodes. In this strategy, the objectives increase the node importance degree and decrease the active power loss subjected to operational constraints. A compound objective function with weight coefficients is formulated to balance the conflict of the objectives. Then a novel quantum particl...

网络重构技术是实现系统优化运行最重要的手段之一。配电网重构通过改变配电系统内开关状态来改变网络结构,以达到降低损耗、消除过载、提高电压质量等目的,较少涉及到网络的结构特征。针对这一问题,本文引入节点重要度作为识别网络关键节点的评价指标,建立降低配电网网络损耗、提高网络节点重要度的配电网重构模型。此模型中采用加权系数法将2个目标函数转化为单一的复合目标函数,解决了目标函数之间相冲突的矛盾。然后,将环网分层编码方案与粒子群算法结合,提出求解上述模型的优化方法。该方法利用分层编码方案随机生成代表配网结构的种群粒子,保证生成的粒子均是可行的拓扑解,避免了繁琐的拓...
