A
12-bus power system has slack bus and 4 voltage controlled buses. For the load
flow analysis using Newton-Raphson method in polar coordinates, the size of the
Jacobian matrix is________.
22 x 22
16 x 16
18 x 18
20 x 20
18 x 18
The
order of the jacobian matrix with one slack bus = 2n-m - 2
m = 4
Order of jacobian matrix
= (2 x 12 - 4 -2 ) x (2 x 12 - 4 - 2) = 18 x 18
Hence,
the correct option is (C).
