Slight correction: Sf = V( mpc.branch(:, F_BUS) ) .* conj(Yf * V); St = V( mpc.branch(:, T_BUS) ) .* conj(Yf * V); carlos. Ray Daniel Zimmerman wrote: In matrix form, you can do the corresponding calculations

Re: Ybus

In matrix form, you can do the corresponding calculations as follows (e.g. for case9): define_constants mpc = loadcase('case9'); [Ybus, Yf, Yt] = makeYbus(mpc); V = mpc.bus(:, VM) .* exp(1j * mpc.bus(:, VA)*pi/180); Sbus = V .* conj(Ybus * V); Sf = V .* conj(Yf * V); St = V .* conj(Yt * V);

Hello, I have a question regarding equations (2) and (3) in the attached picture. I am not sure equation (3) is correct. But *sj* is the power injection and *f{i,j}* is the power flow. I am a littel bit confused, how should I calculate y*{j,k} and *Yjk* in Matpower? According to the attached
