The paper presents the implementation of the fast-decoupled load-flow technique for real-time monitoring of power systems in the presence of metering inaccuracies and data-acquisition failures. The real-time load-flow solution with mode injections and redundant line flows, using the fast-decoupled load flow, is much faster and requires less computer storage than that using conventional Newton-Raphson method, but still provides the same accuracy. Results of this analysis for a.e.p. 30-busbar test system are included for illustration.
