Flow Control Min Impedance

Units:	pu
Mode:	Input Only
Multi-band:	False
Default Value:	0
Validation Rule:	Any Value
Key Property:	No
Description:	Min Impedance

Flow Control Min Impedance is user specified Impedance limits for DSR, TCSC and MSSR type of devices. The Impedance limitation can be derived as a function of line flow:

Flow_FC ≤ - Flow_Line x X_min / (X_Line) If Flow_Line is positive ( Flow_Line >0) Flow_FC ≥ - Flow_Line x X_min / (X_Line) If Flow_Line is negative ( Flow_Line <0)

Therefore, the Min Impedance input is applied as flow/angle limits and replacing the user input Max Angle.Note that Min Impedance must be smaller than or equal to Max Impedance.
