I would like to know how to solve problem 3.60 using PowerWorld. I have posted the problem above and the example 3.13 that the problem refers to. This problem is from the Power Sytem Analysis and Design 5th edition book by J. Duncan Glover.

PW 3.60 PowerWorld Simulator case Problem 3.60 duplicates Example 3.13 except that a re- sistance term of 0.06 per unit has been added to the transformer and 0.05 per unit to the transmission line. Since the system is no longer lossless, a field showing the real power losses has also been added to the one-line. With the LTC tap fixed at 1.05, plot the real power losses as the phase shift angle is varied from - 10 to +10 degrees. What value of phase shift minimizes the system losses? EXAMPLE 3.13 Voltage-regulating and phase-shifting three-phase transformers Two buses abc and a'b'd' are connected by two parallel lines Ll and L2 with positive-sequence series reactances XL1 = 0.25 and XL2 = 0.20 per unit. A regulating transformer is placed in series with line Ll at bus a'b'd'. Deter- mine the 2 x 2 bus admittance matrix when the regulating transformer (a) provides a 0.05 per-unit increase in voltage magnitude toward bus a'b'd' and (b) advances the phase 3 toward bus a'b'c'. Assume that the regulating transformer is ideal. Also, the series resistance and shunt admittance of the lines are neglected
