There is a 3-bus bar system.
On bus1 there is the generator: 30MVA, cosφ=0.8. So active power = 30*0.8=24 MW. And Reactive power=18 MVAr.
On Bus3, there is the load: 15 MVA, cosφ=0.9. So active power = 15*0.9=13.5 MW, Reactive demand=15*sinφ=6.54 MVAr.
The concept of power factor has to do...
Value of Lost Load (VOLL) is the value of the demand curtailed and is approximately 30,000 £/MWh. Ie this is the cost of not
supplying 1 MWh to the consumers.
However, demand is not only MWh, but it is also MVAr. Do you have an idea of the cost of not supplying 1 MVAr to the load...
