Résumé : In this paper we present a supervisory strategy for load/frequency control problems in networked multiarea electrical power systems. The proposed strategy exploits a recently developed constrained control methodology named Parameter Governor, which is based on predictive control ideas and combines in a unique framework the actions of Reference and Offset Governors. The supervisor reconfigures the nominal frequency set-points and adds offsets to the input terminals of the generation units of each area in order to avoid operative constraint violations when unexpected load changes and/or failures occur. Such a reconfiguration capability is achieved by exploiting the inherent physical redundancy of the power grid and allows, if effective, the enhancement of the overall fault tolerance. The effectiveness of the proposed approach is demonstrated on a two-area power system subject to coordination constraints on maximum frequency deviations, exchanged and generated powers.
