摘要
建立了含分布式电源的配电网重构问题数学模型,重点研究了求解该问题的混合型粒子群算法.针对该算法稳定性差以及收敛速度慢等缺点,提出了改进算法的3个解环启发式原则.并利用一个实际算例对算法的改进效果做了检验.结果表明:针对该问题,改进后的混合型粒子群算法的稳定性和计算效率均有明显提高.
The mathematical model of distribution network reconfiguration which contains distributed generators is established. The research of hybrid particle swarm optimal algorithm, which has been used to deliberate the reconfiguration problem, is mainly focused in this paper. For low computational efficiency and poor stability of particle swarm algorithm, three heuristic principles are established to ameliorate the efficiency and the stability of the algorithm. Using IEEE 33 node distribution system as the object, the model and the algorithm was validated. It turned out that the refined hybrid particle swarm optimal algorithm can work with the problem of distribution network reconfiguration which contains distributed generators more efficient and more stable.
