andes.routines.cpf

Continuation Power Flow (CPF) routine.

Traces the PV curve from a solved base case toward a target loading using a predictor-corrector method. The predictor uses a tangent vector; the corrector solves a standard power flow at fixed lambda.

Classes

ArcLengthParam()	P = ||dx||^2 + dlam^2 - step^2.
CPF([system, config])	Continuation Power Flow routine.
NaturalParam()	P = lam - lam_prev - step.
PseudoArcLengthParam()	P = z' * dx + z_lam * dlam - step.
