Subject: RE: addmitance matrix(zbus), noda
Dear Shri,
Thank you for your response!
How can I calculate the shunt addmitance of a line jk (yj->k) in pu?
For instance, the 24 bus system has ysh=0-j100(MVAR) , but this is the bus(->6)
shunt addmitance matrix. How can I obtain the shunt addmitance of a line?
Thank you in advance,
Kind Regard

Dear Matpower community
I would like to block all the messages which are being poped out during

results but if my case cannot get converge, I see some messages regarding
the mathematics solvers saying the matrix is singular fo

Dear Shri, Ray
Thank you very much for your response.
I constructed the Ybus matrix and I found the voltage bus from
Vf(f,1)=results.bus(f,VM)*exp(1j*results.bus(f,VA)*(pi/180))*mpc.bus(f,10);
So in order to define the nodal currents in a 4 bus system I have to do the
following calculations??
I
