基于改进遗传算法的配电网重构研究
|
摘要
为了获取配电网中支路电流并尽可能的降低系统的功率损耗,文中提出了一种基于改进遗传算法的配电网重构方法,建立了以系统功率损耗最小化为目标的配电网重构模型,结合辐射型配电网潮流计算分支电流,并对遗传算法的染色体编码,适应度函数和交叉变异模式进行了改进,避免了计算结果的早熟收敛。结合IEEE-16和IEEE-33的配电网系统进行测试,验证了所提改进遗传算法在配电网重构优化的有效性。
In order to obtain branch current in distribution network and reduce power loss as much as possible,this paper presents a reconfiguration method of distribution network based on improved genetic algorithm,establishes a reconfiguration model of distribution network with the objective of minimizing system power loss,and calculates branch current with power flow of radial distribution network. Chromosome coding,fitness function and cross variation mode are improved to avoid premature convergence of the calculation results. The validity of the improved genetic algorithm is verified by testing the distribution network system of IEEE-16 and IEEE-33.
