1.0 The Admittance Matrix C - Iowa State University
www.engineering.iastate.eduWe make several observations about the admittance matrix given in eqs. (6) and (7). These observations hold true for any linear network of any size. 1. The matrix is symmetric, i.e., Y ij =Y ji. 2. A diagonal element Y ii is obtained as the sum of admittances for all branches connected to bus i, including the shunt branch, i.e., ¦ z N k k i Y ...

If there is no mutual coupling between the elements, the primitive admittance matrix y can be obtained by inverting the primitive impedance matrix z. The matrices z and y are diagonal matrices. In the case, the self-impedances are equal to the reciprocals of the corresponding self ...

In that case, it is yij = gij +jbij with bij is negative. If the DC-OPF does not converge, check that the admittance matrix B is correct!
