Hi
this codes helped me to extract load bus currents but it is unable
to give me generators currents (PV & Slack node).how can i do that ???
please guide me

I assume you are referring to bus load currents? If so, you can use
the fact that s = v * conj(i) to compute them. So Id (the vector of
bus load currents) can be computed from Sd (the vector of complex
powers to the loads) and V (the vector of bus voltages) as follows:
j = sqrt(-1);
V = bus(:, VM) .* exp(j * pi/180 * bus(:, VA));
Sd = bus(:, PD) + j * bus(:, QD);
Id = conj(S ./ V);
Hope this helps,
