### Goals

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.

Content

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
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 calculation of ATC
• The regulator of energy markets: the role, scope and areas of intervention

Prerequisites

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

Tests

The mark of this module consists of 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 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.

CC 65% + CT 35%

The exam is given in english only
