考虑发输配一体的电力系统主网的无功优化研究

以有功网损最小为目标函数建立了电力系统无功优化的数学模型,对于目标函数中的无功电压越界和发电机无功越界点,采用罚函数予以解决.对无功优化问题的求解采用遗传算法,针对遗传算法应用于求解无功优化等复杂非线性优化问题中容易发生"早熟"和收敛速度慢等问题,作了一些改进.通过改进,遗传算法能够跳出局部最优解,增强了全局寻优能力,...

Reactive Power Optimization Research on the Main Power Network Considered the Generation,Transmission and Distribution

Reducing active power loss is considered of the main object function.The model of reactive optimization was established based on these.And the penalty function is considered to deal with variables violating the constraints.In this paper,genetic algorithm is applied in solution of reactive power optimization.Aiming at premature and slow convergent speed which happens easily in the cause of solving reactive power optimization that belongs to complicated Non-linear optimization,this paper made some improvement...
