The convergence characteristics is a prime importance in decoupled Newton-Raphson load flow calculation, since it exhibits often convergence instability, particularly in heavy load levels. It is known that any meaningful improvement is of no use. However, it is found that some slight modifications using quadratic performance function show better stability and remarkable reduction of iteration steps. In a real-scale power-system, improved convergence is demonstrated.
