6.50 Open PowerWorld Simulator case Example 6_13. Plot the variation in the total system

real power losses as the generation at bus BLT138 is varied in 20-MW blocks between

0 MW and 400 MW. What value of BLT138 generation minimizes system losses?

Repeat Problem 6.50, except first remove the 138-kV line from RAY138 to BOB138.
