hello everyone ...
can any one please summarize me the differences between Newton Raphson & Gauss Seidel Methods in load flow study !? I'll be really thankful

i'm an EE and i have no idea what a "load flow study" is.
the NewtonRaphson and GaussSeidel are two different things. as best as i can tell GaussSeidel is sorta equivalent to what we usually call Gaussian elimination, but i may be wrong. both are for solving a set of N linear equations with N unknowns. i don't imagine there are too many problems (like multiple, equallyvalid solutions) if the N equations are all linearly independent. NewtonRaphson is for solving for the roots of N nonlinear equations. it's an iterative method that converges on a result. there are possibilities of the thing not converging on a solution, or sometimes converging on a valid solution, but it isn't the set of roots that you want. a set of N nonlinear equations might have more than one result set of the N unknowns.

thanks for your explanation , I meant with load flow study , power flow study in power system

Differences between Newton Raphson & Gauss Seidel Methods ?
okay, whatever the application is, the Gauss Seidel is for a system of linear equations and NewtonRaphson is for a single nonlinear equation or a system of nonlinear equations.
