Dear All,I am working on optimal power flow to find the contingency (N-1)
situation of the system. For some of the line outage, certain output pops out

Newton's method power flow (power balance, polar) did not converge in 10
iterations.
>>>>> Did NOT converge (7.38 seconds) <<<<<
What to do to correct this error. It would be of great help.
