Order reduction of the dynamic model of a linear periodic system Part II: frequency dependent lines

Summary form only given. The methodology for the order reduction of the dynamic model of a linear weakly periodic system is applied here to the case when the power network includes frequency dependent transmission lines. The technique for obtaining the external equivalent of the network is described. A comparison is given between systems having lines with constant or frequency dependent parameters. Time domain simulations have shown that the reduced order equivalent leads to fast and accurate results
