Y is the admittance matrix; V is the vector of the bus voltage. Let us consider the figure given below. From the above figure, the (3×3) admittance matrix is formed as shown below. The diagonal elements of the Bus Admittance matrix are known as self-admittances and the off-diagonal elements are known as mutual admittances. In this paper, an analytical method of computing the admittance matrix is introduced that facilitates the stability analysis of DC micro-grid systems, in presence of constant power loads (CPLs). Due to their nonlinear behaviour, CPLs can yield instability in DC micro-grids; an effect referred to as ‘negative impedance instability’. ...Note that the matrix Y + Y net is the nodal admittance matrix according to circuit theory [60], and the det(Y + Y net )-based stability criterion is the same as the determinant det(Y node )-based ...02/23/07 The Admittance Matrix 1/5 Jim Stiles The Univ. of Kansas Dept. of EECS The Admittance Matrix Consider again the 4-port microwave device shown below: In addition to the Impedance Matrix, we can fully characterize this linear device using the Admittance Matrix.
