सारांश	The Newton-Raphson method is a powerful iterative technique for solving the nonlinear power flow equations in electrical power systems. Introduced by Tinney and Hart in 1967, it became the industry standard for computing steady-state voltage and power distributions across transmission networks. The method uses Jacobian matrix formulations to rapidly converge to the true operating point.	The Fast Decoupled Load Flow (FDLF) method, introduced by Stott and Alsac in 1972, exploits the weak coupling between active and reactive power in power systems to accelerate convergence beyond standard Newton-Raphson. By decoupling the equations and using constant, approximate Jacobians, it reduces computation per iteration while maintaining acceptable accuracy for most practical systems. This method remains widely used in operational software for its speed and numerical stability.
