When compute net injection at generator buses in the m file doSE.m line
107-110, the local PD and QD are include.
%% compute net injection at generator buses
gbus = gen(:, GEN_BUS);
Sgbus = V(gbus) .* conj(Ybus(gbus, :) * V);
Sgen = Sgbus * baseMVA + (bus(gbus, PD) + j*bus(gbus, QD)); %% inj S +
local Sd
While when compute partial derivatives of the complex bus power injections in
dSbus_dV.m line 9, local PD and QD are unincluded.
% S = diag(V) * conj(Ibus) = diag(conj(Ibus)) * V
Can the sub-matrix of z_est real(Sgen(idx_zPG)) and the sub-matrix of H
dPG_dVa(idx_zPG, nonref) dPG_dVm(idx_zPG, nonref) match?
Best regards!
