Abstract

See full text

A new approach in contingency analysis is presented based on a modular method for power flow calculation. The proposed method exploits reuse of power flow data for modules not affected by an outage. The method minimizes the number of necessary computations and matrix inversions in contingency analysis; this is achieved by recalculating only the modules affected by the change and reusing data from the original system for all other modules.
