- to understant the role of power electronics interfaces to control and protect electrical networks.

Content(s)

This course unit is divided into three parts :

Modelling and management of electrical networks (N. Hadjsaid, R. Caire, 10h CM, 12h BE, 4 h of personnal work)
-----------------------------------------------------------------------------------------------
The course focuses on links between electrical constraints of grids (e.g. Kirschhoff laws) and financial transactions (ewchanged MWh between producers and consumers). The sections are :
o Introduction on electrical networks
o Rule of electrical grids
o Power fluxes, Kirschhoff laws
o Modelling of electrical grid for load-flow calculations
o Per-Unit transformation
o Economic dispatching
o Introduction to Optimal Power Flow calculation

Power electonics converters (J.-L. Schanen, 12h CM, 8h TD, 4 h of personal work)
o Introduction. Recall on choppers
o Switching power supplies
o Rectifiers with thyristors
o PWM Inverter
o PEFC, FACTS and active filtering

Design and control of distributed sources (D. Riu, 14h CTD, 4h BE, 10h of personal work)
-------------------------------------------------------------------------------------------
o Impact of distributed sources on electrical networks
o Design and interface of PV sources : analysis of production, modelling of PV cells and networks, design of PV network, design of power electronics converters, design and synthesis of control loops (MPPT, control of grid currents).
o Design and interface of Proton Exchange Membrane Fuel Cell (PEMFC) systems : electrical circuit modelling, design and control of power electronics converters.
o Dynamic modelling of power electronics converters for ancillary services to grid : space-vector modelling of three-phase systems (Concordia and Park reference frames), modelling of three-phase inverters, control loops of grid currents.
A project allows students to design a PV plant for different applications.
