Enforcing passivity for admittance matrices approximated by rational functions.

Enforcing passivity for admittance matrices approximated by rational functions.

A linear power system component can be included in a transient simulation as a terminal equivalent by approximating its admittance matrix Y by rational functions in the frequency domain. Physical behavior of the resulting model entails that it should absorb active power for any set of applied voltag...
