Consider a power system with N buses, of which P are generator buses and the remaining Q are load buses (where there is no generation).
Assume that there are no reactive power-limit violations at the generator buses.
What is the size of the Jacobian matrix in the Newton-Raphson load flow method?
A
2N × 2N
B
(2N − 1 − P) × (2N − 1 − P)
C
(2N − Q) × (2N − Q)
D
(P + Q) × (P + Q)

Correct : b
