Good start! The missing pieces are expressions for generator injection currents.

Network interfaces:

V_{d,3} = V_{3,r}\sin(\delta_3) - V_{3,i}\cos(\delta_3) + I_{d,3} R_{a,3} -I_{q,3} X_{qpp,3}
```
```math
V_{q,3} = V_{3,r}\cos(\delta_3) + V_{3,i} \sin(\delta_3) + I_{d,3}X_{qpp,3} + I_{q,3}R_{a,3}

The network interface should include expressions for generator injection currents into the bus. Injection currents are used in the equations for $I_q$ and $I_d$, but you need explicit expressions for $I_{G,r,k}$ and $I_{G,i,k}$ in order to be able to assemble bus equations.

Generators may have their own labels that do not coincide with bus labels. For simplicity, in this case, you can switch bus 2 and 3 labels.
