Repeat Problem 5.43, but now vary the load reactive power, assuming the load real power is fixed at $1000 \mathrm{MW}$.

Data From Problem 5.43:-

Open PowerWorld Simulator case Example 5.4 and graph the load bus voltage as a function of load real power (assuming unity power factor at the load). What is the maximum amount of real power that can be transferred to the load at unity power factor if we require the load voltage always be greater than 0.9 per unit?

Data From Example 5.4:-

Neglecting line losses, find the theoretical steady-state stability limit for the 300-km line in Example 5.2. Assume a 266.1-2 surge impedance, a 5000-km wavelength, and Vs = VR = 765 kV.
