摘要
指出网络重构是配电系统运行和控制的手段,也是配电管理系统的重要内容。考虑配电网运行特点,建立了以有功网损最小为目标的配电网重构数学模型,并计及潮流、电压、容量及辐射状运行等约束条件。针对该模型的特点,采用一种新型混沌遗传混合算法对配电网进行重构计算,该算法既具有遗传算法的全局性和并行性,又具有混沌搜索的遍历性和快速性。将该算法用于IEEE33节点系统重构计算,并与重构前、单一遗传算法重构结果进行比较,证明了所提出混沌遗传混合算法的有效性和快速性。
Network reconfiguration is the operating and controlling means of distribution system and is of importance in distribution management system. Considering the operation characteristics of distribution network, the model for distribution network reconfiguration is proposed in this paper, which intends to minimize the network loss with many restrictions such as power flow, voltage, power capacity and radial operation. To solve this complicate problem, a chaos genetic hybrid algorithm is employed, which possesses both the characteristics of wholeness and parallelism belonging to genetic algorithm and the characteristics of ergodicity and rapidness belonging to chaos search. The hybrid algorithm is used for the reconfiguration of IEEE33 bus network and proved valid and rapid by comparing with the reconfiguration results of single genetic algorithm.
