Flow Control Min Voltage

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

Flow Control Min Voltage is user specified voltage limits for SSSC and DSSC type of devices. The voltage limitation can be derived as extra bound for Flow Control phase angle:

θ_FC ≥ (V_min / V_nom) x cos(θ₁ - θ₂)/2

Assumption is introduced here to adopt the nonlinear equation to linear programming:

Assume: cos(θ₁ - θ₂)/2 = 1

Therefore, the Min Voltage input is applied as angle limits and replacing the user input Min Angle:

θ_FC ≥ (V_min / V_nom)

Please note that V_nom is the nominated line voltage, which is read from Node Voltage. If Node Voltage is not defined, the Flow Control Min Voltage will be ignored.
