For the system from Problem 2.32, assume that half the time the load is 10 Mw and 5 Mvar, and for the other half it is 20 MW and 10 Mvar. What single value of Qan would minimize the average losses? Assume that Quip, can only be varied in 0.5 Mvar steps. Reference of problem 32 In PowerWorld 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 ?. The load is compensated with a capacitor whose out-put apɔ can be varied in 0.5 Mvar steps between 0 and 10.0 Mvars. What value of ans minimizes the real power line losses? What value of na minimizes the MVA power flow into the feeder?
