输电网9节点区间潮流计算程序，修改数据可用-IEEE 9 interval power flow

随着电力系统运行环境的复杂化,系统运行状态的不确定性因素多元化,给电力系统分析带来了新的挑战。区间潮流因其建模简单等优点而成为不确定性潮流分析的主流方法之一。(Interval power flow program, which can be used to calculate interval power flow)

区间蒙特卡洛潮流算法，当输入变量为确切区间变化时，采用牛拉法计算在该输入变量下的电网区间状态值(The interval Monte Carlo power flow algorithm is used to calculate the state value of the power grid interval under the input variable when the input variable is the exact interval change.)
