Extended decomposition-simulation approach for multi-area reliability calculations

The authors describe the extended decomposition simulation approach for multi-area reliability calculations. The approach differs from the original decomposition-simulation approach in that area loads are modeled by a multi-area load model, simulation indices are compared differently, and frequency indices are computed. The authors present a brief description of the overall approach. Algorithms for computing indices in the simulation approach and frequency due to generation changes are described. These algorithms are aimed at improving the accuracy of the simulation indices and the efficiency of the procedure computing frequency due to generation changes. The latter algorithm is based on a set of well-defined relationships among the sets obtained in the decomposition approach. System studies are presented to illustrate the merits of the proposed algorithms.
