Résumé
This PhD investigates the potential contributions of flexibilities in Low Voltage Smart Grids. These networks are intrinsically different from Medium and High Voltages networks, so that the control of LV flexibilities cannot be directly taken from MV and HV networks, and new methods have to be developed. The contributions of these flexibilities is studied through two main benefits: improved network operation and peak shaving.
The first benefit focuses on maintaining the critical variables within the admissible constraints. The objective is to manage the network closer to its limitations, reducing the need for margins, and therefore the need for upscaling. This is especially true in case of significant insertion of distributed generations or electric vehicles. The studied flexibility is the coordinated management of decentralized generations (active and reactive powers, phase switch) and tap changer. The main contribution of this PhD to this problem is that the network characteristics are not required.
The second benefit concerns the reduction of the peak consumption, either at the MV/LV transformer, either at the national level. The studied flexibility is the shedding of electric heating for a short time, followed by a rebound when the heating system is turned back on.
