Continuation power flow¶
The continuation power flow is a technique that traces a trajectory from a base situation given to a combination
of power 
and voltage 
, to another situation determined by another combination of power
. When the final power situation is undefined, then the algorithm continues until the Jacobian is singular,
tracing the voltage collapse curve.
The method uses a predictor-corrector technique to trace this trajectory.
