Question

While the fast decoupled power flow usually takes more iteration to converge, it is usually significantly faster than the Newton-Raphson method.

(a) True (b) False

Short answer

The correct answer is (a) true.

Step-by-step solution

Definition of fast decoupled method.

The rapid decoupled load flow software, which uses thin matrix techniques, requires less storage and runs faster. Still, updating the program to respond to new research, such as power grid security and power flow continuity, is made more difficult.

Determine the fast decoupled power flow method.

The Jacobian values are not updated in successive iterations in the fast decoupled power-flow methodology. Hence it takes more iterations to converge than the Newton-Raphson method.

Therefore, the given statement is true.
