The gauss-Seidel iterative method can be used for solving a set of

### Right Answer is:

The linear algebraic equation only

#### SOLUTION

- Load flow study determines the operating state of the system for a given loading.
- Load flow solves a set of simultaneous non-linear algebraic power equations for the two unknown variables
**(|V| and ∠δ)**at each node in a system. - The output of the load flow analysis is the voltage and phase angle, real and reactive power (both sides in each line), line losses, and slack bus power.
- Gauss seidel, Newton Raphson, and the Fast decoupled load flow method are the different load flow methods.
**The number of iterations required for convergence of a load flow algorithm increases significantly with the increase of the number of buses with the G-S load flow algorithm.**- The fast decoupled load flow method gives an approximate load flow solution because it uses several assumptions. Accuracy depends on the power mismatch vector tolerance.
- The fast decoupled load flow method is an extension of the Newton-Raphson method formulated in polar coordinates with certain approximations, which results in a fast algorithm for load flow solution.
- The fast decoupled method requires a greater number of iterations than the Newton-Raphson method.

**The advantages of the Gauss-Seidel method are:-**

- A simple algebraic equation is used hence it requires less number arithmetic operations to complete iteration and therefore the time required for each iteration is less
- The need for computer memory is less.
- This method is most suitable for a small size network.
