CONTROLE DE TENSION AUTO ADAPTATIF POUR DES PRODUCTIONS DECENTRALISEES D'ENERGIES
CONNECTEES AU RESEAU ELECTRIQUE DE DISTRIBUTION

Abstract : Voltage fluctation problems in the distribution grid are involved by the connection of
distributed generators (DG). Indeed, the productions of these generators may influence the
network voltage map and the loadflow. These technical problems can lead to critical
overvoltages. The current structure of the network is not adapted to a high insertion of DG.
Indeed no telemetrie and communication agents are placed in the distribution grid. It is difficult
to imagine solutions for voltage control using communications and mesurements because of the
high quantities of information and of the costs involved by these solutions.
Thus, our study relates the development of an autonomous and intelligent voltage control
of such DG, using local informations. This control permits to carry out on the grid a global
voltage control without DG coordination using communications.
This contol is able to adapt its objectives in an optimal way, to keep the voltage level
between network limits.
Following the development of this control, software tests and practical tests were carried
out to improve the operation of such a control on various network configurations and various
productions, to prove the appliance of such a system. This work has been completed by the
comparison between this local approach and a coordinated voltage control using DG.
