System Constraints part 2
Voltage constraints
The upper limit of phase angles is defined regarding the
transient stability of power systems On the other hand, the
lower limit of the angles is defined taking into account
achieving an efficient utilization of transmission facility
Typical operating angle of transmission line lies
between 30° - 45°
Voltage constraints
Vmin ≤ Vn ≤ Vmax
δ min ≤ δ n ≤ δ max
Where: is the magnitude of node angle with an angle of dn at
