Abstract
This paper describes a decomposition methodology applied to the multi-area optimal power fiow
problem in the context of an electric energy system. The proposed procedure is simple and efficient, and
presents sorne advantages with respect to other common decomposition techniques such as Lagrangian relaxation
and augmented Lagrangian decomposition. The application to the multi-area optimal power fiow
problem allows the computation of an optimal coordinated but decentralized solution. The proposed method
is appropriate for an Independent System Operator in charge of the electric energy system technical operation.
Convergence properties of the proposed decomposition algorithm are described and related to the
physical coupling between the areas. Theoretical and numerical results show that the proposed decentralized
methodology has a lower computational cost than other decomposition techniques, and in large large-scale
cases even lower than a centralized approach.
