1. Following figure shows the one-line diagram of a two bus system. Take bus 1 as slack bus, bus 2 as load (PQ) bus. Neglect the shunt charging admittance. Obtain the bus admittance matrix YBUS and find V2 and 82, power flows and line losses using Decoupled load flow method. All the values are given in per unit on 100MVA base. Use a tolerance of .001 for power mismatch. 2 Z12= 0.12+j0.16 P12=1.0pu Q12=0.5pu Slack bus V;=1.0/0" pu

1. Following figure shows the one-line diagram of a two bus system.
Take bus 1 as slack bus, bus 2 as load (PQ) bus. Neglect the shunt
charging admittance. Obtain the bus admittance matrix YBUS and find
V2 and 62, power flows and line losses using Decoupled load flow
method. All the values are given in per unit on 100MVA base. Use a
tolerance of 0.001 for power mismatch.
