System AB is connected to system BC via a 1000 MW tie-line. The total capacity of the online units and the demand of system AB are 10000 MW and 8500 MW, respectively. The total capacity of the online units and the demand of system BC are 20000 MW and 17000 MW, respectively. System AB is importing 500 MW from system BC and all units operate with a common governor droop setting of 5% for both systems.

Analyse several voltage and current situations in different loading scenarios in a simplified radial (transformer to consumption) medium-voltage power system example. There are only 2 nodes in the 35 kV line – node 0 from the 110/35 kV and node 1 with one consumer. The physical characteristics of the line and the loading scenarios are individualized for each student – please see the attached file Excel “WM9P3 Task1 data” for your particular data set.  Briefly reflect on the complexity of the calculations for known input or output voltage, as well as for fixed or voltage-dependent consumption in this simple power system model.  Analyse and discuss the sensitivity of the voltage drop [in % of amplitude and the degrees of phase] with respect to the current level [in %] and to the power factor.
