16、是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。多数方程 不存在求根公式，因此求精确根非常困难，甚至不可能,从而寻找方程的近似根 就显得特别重要。方法使用函数f(x)的泰勒级数的前面几项来寻找方程f(x)=0 的根。牛顿迭代法是求方程根的重要方法之一，其最大优点是在方程f(x)二0的 单根附近具有平方收敛，而且该法还可以用来求方程的重根、复根。相应程序详见附件1.2.1.1 满发满载运行方式下计算在这种运行方式下，三台机组全部开启,各自保留10%作为功率裕度，重 用负荷占发电量7% ,负荷为最大负荷。此方式下，节点1为平衡节点，节点2、 3、4、5、6、7为PQ节点，节点8、9
