I. Introduction:

\(\bullet\) This WSCC 3 Machines, 9 Bus Test Case (known as P.M Anderson 9 Bus) represents a simple approximation of the Western System Coordinating Council (WSCC) to an equivalent system with nine buses and three generators.
\(\bullet\) This test case consists of 9 buses, 3 generators, 3 two-winding power transformers,  6 lines and 3 loads.
\(\bullet\) The base KV levels are 13.8 kV, 16.5 kV, 18 kV, and 230 kV. The line complex powers are around hundreds of MVA each. As a test case, the WSCC 9-bus case is easy to control, as it has few voltage control devices.
