Example 6.1. A 750 kV transmission line has 0.0175 p.u. series reactance (the series resistance and the shunt admittance are ignored in this example). The terminal bus voltage magnitudes are 0.984 and 0.962 p.u. and the angle difference is 10◦ . Calculate the sensitivities of the active and reactive power flows with respect to voltage magnitude and phase angle.
