Admittance matrix
BUS IMPEDANCE MATRIX. The impedance matrix is given by Z bus = Y bus-1 Since the bus admittance matrix is symmetrical, the bus impedance matrix is also symmetrical around the principal diagonal. In bus impedance matrix, the elements on the main diagonal are called driving point impedance of the buses or nodes and the off-diagonal elements are called the transfer impedances of the buses or nodes.Expert Answer.
