Power measurement in AC grid: measure of active and reactive power for various loads
Studies of the transient response due to load or power disconnection
Electrical model of photovoltaic cell, PV modeling for simulation and control 1h C 2h TD
The PV cells electrical models are presented. The use of Lambert function for PV systems simulation purpose is introduced. Maximum Power Point tracking (MPPT) algorithms are presented (Perturb&Observe, conductance methods) with their associated power converter. A complete simulation realized with Matlab/Simulink including PV modeling, power electronic converter and MPPT algorithm will be developed by the students.
PV Power generation to the grid - 2h C 4h TD
An introduction to the transfer of power between voltage generators is presented. The PV power plant architecture, injection of power into the 3-phases AC grid and constraints is then introduced. The grid code constraints are finally discussed. A complete simulation of PV plant realized with Matlab/Simulink including PV modeling, power electronic inverter, Power injection to the grid will be developed by the students in two parts. The first one deals with the control of the active and reactive powers injected to grid and the second one details the MPPT algorithm implementation in the PV plant case.
