PF

Type for power flow routines.

Common Parameters: pd

Common Vars: pg

Available routines: DCPF, PFlow, CPF

DCPF

DC power flow, overload the solve, unpack, and run methods.

Notes

1. DCPF is solved with PYPOWER runpf function.

2. DCPF formulation is not complete yet, but this does not affect the results because the data are passed to PYPOWER for solving.

Vars

Name	Symbol	Description	Unit	Source	Properties
pg	\(p_{g}\)	Gen active power	p.u.	StaticGen.p
aBus	\(a_{Bus}\)	bus voltage angle	rad	Bus.a
plf	\(p_{lf}\)	Line flow	p.u.

Parameters

Name	Symbol	Description	Unit	Source
x	\(x\)	line reactance	p.u.	Line.x
tap	\(t_{ap}\)	transformer branch tap ratio	float	Line.tap
phi	\(\phi\)	transformer branch phase shift in rad	radian	Line.phi
pd	\(p_{d}\)	active deman	p.u.	StaticLoad.p0

PFlow

AC Power Flow routine.

Notes

1. AC pwoer flow is solved with PYPOWER runpf function.

2. AC power flow formulation in AMS style is NOT DONE YET, but this does not affect the results because the data are passed to PYPOWER for solving.
