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
Detail:

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.
