In Power World Simulator case Problem 2_32 (see Figure 2.28) a 8 MW and 4 Mvar load is supplied at 13.8 kV through a feeder with an impedance of 1

+ j2 N. The load is compensated with a capacitor whose out-put, Qcap, can be varied in 0.5 Mvar steps between 0 and 10.0 Mvars.What value of qcap minimizes the real power line losses? What value of Neap minimizes the MVA power flow into the feeder?
