2. The Fig. P2.1 shows the one-line diagram of a simple four-bus system. Table P2.1
gives the line impedances identified by the buses on which these terminate. The
shunt admittance at all the buses is assumed negligible
(a) Convert the network impedances to admittances.
(b) Obtain the bus admittance YBUS assuming that the line shown dotted is not
connected.
(c) (i) What modifications need to be carried out in YBUS if the dotted line is
now connected.
(ii) Obtain the new YBUS.
