| 摘 要： | 牛顿-拉夫逊法是当前广泛采用的电力系统最优潮流的计算机算法,其收敛性好,但该法对初始值要求比较严格。拟牛顿法,它减小了牛顿法的计算量,同时保留了牛顿法的优点,在综合衡量一个算法各项指标的情况下,拟牛顿法的声誉很高。最后通过一个算列,验证了在潮流计算中拟牛顿法比牛顿法更具优越性。

| Abstract: | Newton-Raphson method is currently widely used in optimal power flow computer algo- rithms, the convergence is good, but the law more stringent requirements on the initial value. Quasi- Newton method, which reduces the amount of computation Newton＇s method, while retaining the advan- tages of Newton＇s method, in the case of the indicators composite measure of an algorithm, to be a high reputation Newton method. Finally, a numerical column, verify the flow calculation in quasi--Newton method has more advantages than the Newton method. |
