基于鸡群优化算法的配电网络重构

鸡群优化算法是模仿鸡群觅食的群体智慧发展而来的生物启发式算法,将鸡群优化算法应用到配电网重构当中,充分利用鸡群优化算法高效的全局和局部搜索能力,快速寻找使配电网在满足约束条件下目标函数最小的网络状态,保证配电网运行的经济性和可靠性。给出了基于鸡群优化算法的配电网重构具体实现流程,以IEEE33节点系统为例,采用鸡群优化算法(CSO)和粒子群算法(PSO)两种算法进行仿真实验,结果表明鸡群优化算法较粒子群算法搜索效率平均提高了11.6%,寻优速度更快更稳定。

Distribution Network Reconifguration Based on Chicken Swarm Optimization Algorithm

The chicken swarm optimization algorithm is a biological heuristic algorithm which imitates chicken swarm foraging of collec-tive intelligence development. The chicken swarm optimization algorithm was applied in distribution network reconfiguration. This algorithm was with the high-efficiency global and local search capability to rapidly look for the network state with minimal objective function meeting the constraint requirements in distribution network, so as to ensure the economical efficiency and reliability of distribution network operation. This paper gave the concrete realization fiowchart of distribution network reconfiguration, took the IEEE33 nodes system for example and carried out simulation experiment with the algorithms of chicken swarm optimization and particle swarm optimization. The results show that the search ef-ficiency of chicken swarm optimization algorithm increases by 11.6% on average than the particle swarm algorithm, and optimization speed is faster and more stable.
