Convergence criteria analysis
WebOct 7, 2009 · Convergence is the state when all nodes have met the mismatch tolerance. The main power flow solution methods are: Gauss-Siedel method – updates the voltage one node at a time until all nodes are within the mismatch tolerance. Generally a slower method than the others that follow. Newton-Raphson method – uses a first order expansion of the ...
