Abstract

The problem of obtaining the correct optimal steady-state operation of an industrial interconnected system, in spite of deficiencies in models of its subsystems, is considered. Hierarchical structures of the integrated system optimization and parameter estimation (ISOPE) technique have recently been proposed for the considered problem, and algorithms have also been derived. A comparative study of the hierarchical ISOPE algorithms is provided. The study includes the existing algorithms and new ones proposed. The new algorithms are based on the use of the augmented Lagrange function. The main emphasis is placed on the simulation study and a comprehensive comparison of the practical effectiveness of all algorithms, both for convex and non-convex problems. The obtained results not only provide a comparison of the convergence speed of various algorithms, but also give insight into the sensitivity of the various algorithms to values of their parameters which have to be specified by the user. These properties are important from a practical point of view. The results also indicate the superiority of some newly introduced algorithms, at least for a given class of problems.
