Load PowerWorld Simulator case Problem 6_46. Plot the reactive power output of the generator at bus 2 as a function of its voltage setpoint value in 0.005 p.u. voltage steps over the range between its lower limit of -50 Mvar and its upper limit of 50 Mvar. To change the generator 2 voltage set point first select Tools, Play to begin the power flow simulation, and then click on the up/down arrows on the bus 2 magenta voltage setpoint field.

Problem 6.46

Load PowerWorld Simulator case Problem 6_46. Using a 100 MVA base, each of the three transmission lines have an impedance of \(0.05+j 0.1 \) p.u. There is a single \(180 \mathrm{MW}\) load at bus 3, while bus 2 is a PV bus with generation of \(80 \mathrm{MW}\) and a voltage setpoint of 1.0 p.u. Bus 1 is the system slack with a voltage setpoint of 1.0 p.u. Manually solve this case using the Newton-Raphson approach with a convergence criteria of \(0.1 \mathrm{MVA}\). Show all your work. Then verify your solution by solving the case with PowerWorld Simulator.
