The bus admittance matrix of the network shown in the given figure, for which the marked parameters are per unit impedances is
When the PV bus is treated as PQ in load flow studies ?
What is the form of the Ybus matrix for carrying out load flow studies by Gauss-Seodal method of a power system having mesh connection of nodes?
In a load flow problem solved by NR-method with polar coordinates, the size of the Jacobian is (50 × 50). If there are 10 PV buses in addition to PQ buses and a slack bus the total no of buses in the power system is.
For a 50 bus power system size of admittance matrix (Y – bus) will be –
Which of the following statements is/are correct?
1) Memory requirement in programming in N-R method is less.
2) N-R method takes more time for solution of each iteration but convergent time is less.
