WSCC 9-Bus System

WSCC 9-bus test system (also known as P.M Anderson 9-bus) represents a simple approximation of the Western System Coordinating Council (WSCC) to an equivalent system with 9 buses and 3 generators. This particular test case also includes 3 two-winding transformers, 6 lines and 3 loads. The base kV levels are 13.8 kV, 16.5 kV, 18 kV, and 230 kV. The single-line diagram of the WSCC 9-bus case is shown below [1]:
