Dynamic equivalent of neighbor power system for day-ahead stability studies

A novel method to construct power system dynamic equivalents for day-ahead stability studies is proposed. It provides a reduced-order model of the neighbor areas of a Transmission System Operator (TSO). When connected to the detailed representation of the TSO zone to be studied, this model is adequate for quick transient-stability studies. The approach is based on recent results in the topic of reduction which allow small size and robust (against daily variations of the grid situation) dynamic equivalents. The methodology is shown on the situation treated by the French TSO (Réseau de Transport d'Electricité — RTE) for its North-Eastern border.
