This paper presents an efficient and reliable algorithm to solve the optimal generation dispatch problem in a robust, flexible and fast way, and which retains the same performances for either a small or a large-scale problem. This algorithm is based on the use of augmented Lagrangian. In order to verify the effectiveness and the performances of the proposed algorithm, it was tested on an electrical power system composed by five power plants linked to an electrical transmission network. The test results show that the optimal solution is obtained with moderate calculation effort and the convergence was very fast and without oscillations. Moreover, the adjustment of the parameters of the method is easy.
