IMPACT DE LA GENERATION D'ENERGIE DISPERSEE DANS LES RESEAUX DE DISTRIBUTION

Abstract : Power systems are undergoing profound changes due to the deregulation of the power industry. One of the consequences of this deregulation is the emergence of dispersed generation in distribution networks. The introduction of this generation within the existing distribution networks cao have important effects that should he carefully assessed. This thesis deals with the identification and assessment of these impacts on distribution networks (voltage, short-circuit currents, stability, critical clearing time ...). These impacts are highlighted by using dynamic simulations and by using small signaIs theory tools (eigenvalues and participation factors). Furthennore, several optimisation algorithms are used in order to insert this dispersed generation in the existing distribution networks in an optimum way (security, enhanced performances ...). Optimisation algorithms (algorithm of Minimax, genetics, simplex and simulated annealing) are also implemented to irnprove the voltage profile of distribution networks with dispersed generation. In addition, sorne of these algorithms are used to coordinate the gains contained in the controllers of the dispersed generations in order to improve the stability of the networks. Influence indices are also defined in arder to identify the influence areas ofthe dispersed generation on the distribution networks.
