Fast Decoupled Power Flow

Fast Decoupled Load Flow (FDLF) metoden, introduceret af Stott og Alsac i 1972, udnytter den svage kobling mellem aktiv og reaktiv effekt i elsystemer til at accelerere konvergens ud over standard Newton-Raphson. Ved at afkoble ligningerne og anvende konstante, approksimative Jacobians reduceres beregningen pr. iteration, samtidig med at der opretholdes acceptabel nøjagtighed for de fleste praktiske systemer. Denne metode anvendes fortsat bredt i operationel software på grund af dens hastighed og numeriske stabilitet.
