摘要 提出了配电网开关优化配置的改进遗传算法。为提高遗传算法的计算速度和收敛效率,采取了以下改进措施:①给出初始种群的生成模型,提高初始种群的适应值;②对染色体进行分段遗传操作,以保证各类开关设备能同步优化;③提出模糊变异的实现方法,以利于优质基因遗传并避免局部最优化;④提出最优染色体的变异机制,以提高算法局部搜索能力。将该算法应用于RBTS-Bus6和实际系统并与普通遗传算法进行比较,结果表明该算法在收敛速度和全局收敛性上均优于普通遗传算法。 An improved genetic algorithm of optimalbreaking devices in distribution networks is presented. Toaccelerate calculation speed and convergence efficiency ofgenetic algorithm, some measures are adopted, they are: (a)giving the generation model of initial population to improve theadaptive value of initial population; (b) conducting sectionalgenetic operations on chromosomes to ensure that all kind ofbreaking devices can be synchronously optimized; (c)proposing the realizing method for fuzzy mutation which isb...
