hello,
I am ding my simulation on WSCC 9-bus to find the transient stability, with 3rd order of generator.i.e states are [delta,omega,Eq']. I did the load flow to find the operating point (at steady state) and Y admittance but I didn't get the good one. Please help me with your suggestions.

We illustrate the DAE models discussed in the previous sectionwith a numerical
example. We consider the popular Western System Coordinating
Council (WECC) 3-machine, 9-bus system [73] shown in Figure 7.4. This
is also the system appearing in [74] and widely used in the literature. The
base MVA is 100, and system frequency is 60 Hz. The converged load-
ow
data obtained using the EPRI-IPFLOW program [75] is given in Table 7.1.
