英文摘要：

In order to seek an intelligent algorithm that is suitable for solving the distribution network reconfiguration issue, a computing platform which employs eight population-based intelligent algorithms is constructed. In the platform, for different algorithms, the distribution network reconfiguration model and the basic loop search module are completely consistent, with the parameters such as population size and elite number being identical. The basic principles and calculation procedures of the eight algorithms are given. The sensitivity of the algorithm parameters is tested, and the performance of the eight algorithms is compared using IEEE 33-bus system. In addition, the adaptability of the algorithms is further compared using the IEEE 16-bus and PG＆E 69-bus test systems. The results show that Stud GA is the most suitable algorithm and BBO comes the second in terms of the average objective function value, the probability of converging to the best solution, the computation time and the adaptability to the systems of different scales, and the other algorithms have inconsistent performance in different test systems. Stud GA is a suitable algorithm for solving the distribution network reconfiguration issue because of its advantages of simple operation, few parameters, short computing time, and high probability of converging to the optimal solution.
