Participation de parcs de production éolienne au réglage de la tension et de la puissance réactive dans les réseaux électriques

Abstract : In this PhD dissertation, we propose various voltage and reactive power regulation algorithms for different connection types of the wind farm to the power network. Three connection types are considered here: a wind farm connected directly to the distribution network, dispersed wind turbines connected to the distribution network and a set of wind farms connected to the transmission system.A closed loop controller (Wind Farm Controller) is proposed in case of a directly connected wind farm to the distribution network.A coordinated voltage control in the presence of on load tap changer (D-CVC) is proposed in case of dispersed wind turbines connected to the distribution network. We also propose a more decentralized version of D-CVC named D2-CVC; this version can be also implemented under multi-agent system (MAS).A multi-level control system is proposed in case of a set of wind farms connected to the transmission system. It allows the wind farms to optimally participate at reactive power balancing in transmission network. All the proposed voltage algorithms are based on a multi-objective optimization function. The experimental implementation of these regulation algorithms is run under RT-Lab real-time simulator. It allows validating their real-time operation and their communication modes before the implementation on a real site.The results of the current thesis show the improvement of distributed generation integration in the power system network
