(1) Load Flow Basics
a) Build the IEEE 14 bus network based on the data provided above.
b) Check the load flow results – bus voltage magnitudes and angles, real and reactive
power generation and consumption.
c) Check the line real and reactive power losses.
(2) Impacts of Compensation Devices on Load Flow
a) Tap changing regulation: Change the tap ratio between Bus 7 and Bus 9 from 1
to 0.98. Check the load flow results.
b) Shunt reactive power compensation: Undo the changes made in a). Connect a
nominal 10MVar shunt capacitor to the lowest voltage bus – Bus 14. Check the
load flow results.

c) Parallel transmission line construction: Undo the changes made in b).
Construct an extra transmission line from Bus 4 to Bus 5, which is exactly the
same as the existing one. Check the load flow results.
(3) Impacts of Network Contingencies on Load Flow
a) Loading level increase: Change the loads connected to Bus 13 and Bus 14 to
18MW/8MVar and 20MW/8MVar. Check the load flow results.
b) Non-slack bus generator out of service: Undo the changes made in a).
Disconnect Generator 2 from the network. Check the load flow results.
c) A major transmission line out of service: Undo the changes made in b).
Disconnect one of the transmission lines from Bus 1 to Bus 2. Check the load
