he purpose of this module is to address the operation of electrical networks in two ways: modeling and computing methods for power grids operation under liberalized markets.


he module content is divided into two parts:

  • Modeling and Computation networks
  • Deregulation: network operation under liberalized markets

The "Modeling and Design of Networks" covers the following chapters:

  • Introduction to the problem of modeling in Large Electric Systems
  • Classification of problems of electrical networks and their timing
  • Matrices Power System:
    o Background on graph theory
    o primitive matrices, incident matrices and transfer matrices
    o Construction of the transfer matrices using the "inspection" method
    o Examples of construction of network matrices
  • Calculation of load Flows
    o Defining the Problem
    o The numerical methods for solving the problem of load balancing
    o Calculation of power transfers
  • Current calculation for systematic short-circuits using network matrices
    o Symmetrical short-circuits
    o Non symmetrical short-circuits
  • Introduction to state estimation

"Deregulation" part covers the following chapters:

  • Networks operations:
    o practical aspects of maintaining the balance of production - consumption
    ? consumption forecast
    ? dynamic constraints of production
    ? production scheduling
    ? load monitoring and security analysis
    o analysis of the various network constraints
  • Interconnections in networks
    o Logical development of interconnections
    o Benefits vs cons
  • Introduction to electricity markets
    o History of the opening of the energy markets in France and around the world
    o Reasons for open markets
  • Market participants and scope of responsibility
  • Market mechanisms
  • Market models
    o Pool / PX, OTC, single buyer ...
    o Example clearing mechanisms in markets
    o Analysis of the mechanisms of price formation
    o Analysis of price trends
  • Ancilary Services
  • Congestion management
  • The adjusting mechanism
  • The calculation of ATC
  • Mechanisms for access to the transmission and distribution
  • The regulator of energy markets: the role, scope and areas of intervention


  • "Electric Energy module", TC1
  • bases on economy


The mark of this module consists of supervised written exam with a coefficient of 0.35 and a continuous assessement with a coefficient of 0.65.

The written exam will be on the deregulation part of the module.
The continuous assessement mark will be the mean of the two following marks :
o Mean of the Power systems modelling and computation labs
o Deregulation project defense

The second session evaluation will remplace the written exam of session 1. It will be a written or oral exam on the deregulation part of the module.

EN 65% + ER 35%

The exam is given in english only FR


The course exists in the following branches:
