This is for 14 The standard database of nodes is in matlab The result of running in , But I can't understand it myself , I'd like to ask for some advice , How to judge whether convergence ? How to get the influence of different start-up methods on power flow convergence ?

Take the answer :

Judge whether convergence or not , You need to judge whether the value you want to ask stays at a value after running iterations . The best way to judge is to make a convergence graph , Like the following figure

It can be seen from the above figure that it finally converges to 0.049

The influence of different startup methods on power flow convergence can be seen from the convergence diagram , The earlier it converges to the optimal value and the smaller the volatility , The better the convergence
