Study on QGA-based Real-time Reconfiguration of Large-scale Distribution Networks

针对大规模配电网的实时重构很难在很短时间内找到最优解的问题,在分析传统的解决方法存在计算时间长、结果精度不足等基础上,提出采用量子遗传算法(quantumgenetic algorithm,QGA)来解决配电网的实时重构,并给出一种新的基于QGA的重构算法——QGA-PR。算例分析表明,该算法能有效进行配电网重构,在较短时间内可获得更低的线路损耗,且能保证配电网的安全和经济运行。

Aiming at the difficulty in obtaining optimal solution for real-time reconfiguration of large-scale distribution networks in short time and on the basis of having analyzed the long calculation time and inaccurate result and so on,the article proposes the adoption of quantum genetic algorithm（QGA） to address the reconfiguration of distribution networks.It also recommends QGA-PR,a new reconfiguration algorithm based on QGA.The example analysis demonstrates that this algorithm can effectively enable the reconfiguration of distribution networks,less line loss in shorter time and moreover ensure safe and economical operation of distribution networks.
