APPLICATION DES ENSEMBLES FLOUS A LA REPARTITION OPTIMALE DE LA PUISSANCE DANS LES RESEAUX ELECTRIQUES

Optimal power flow calculation (OPF), used to optimize specific aspects of power system operations, usually employ standard mathematical programming techniques. These techniques are not suitable to handle many practical considerations encountered in power systems, including the uncertainty of the operational constraints [1]. They can be relaxed temporarily, if necessary, to obtain feasible solutions. For taking well into account this type of constraints, one proposes in this work the application of a method based on fuzzy sets to the OPF problem. The developed method has been tested on standard scale power systems (IEEE30bus).
