In power engineering, Kron reduction is a method used to reduce or eliminate the desired node without need of repeating the steps like in Gaussian elimination. It is named after American electrical engineer Gabriel Kron. .
Kron reduction is a useful tool to eliminate unused nodes in a matrix. For example, three linear elements linked in series with a port at each end may be easily modeled as a 4X4 of. .

The concept behind Kron reduction is quite simple. Y-parameters are measured using nodes shorted to ground, but unused nodes, that is nodes without ports, are not necessarily grounded, and their state is not directly known to the outside. Therefore, the Y.
