This paper presents a mathematical framework for the solution of the economic dispatch problem. In this paper, the application of a decomposition method for the solution of this problem is emphasized. The system's optimization problem is decomposed into several subproblems corresponding to specific areas in the power system. The upper bound technique along with the decomposition method are applied to a 16-bus system and a modified IEEE 30-bus system, and numerical results are presented for larger systems. These results indicate that specific formulation of the reactive power optimization and the application of the decomposition procedure will facilitate the solution to the problem. This algorithm can be applied to a large-scale network and its solution represents a significant reduction in the number of iterations and the required computation time.
