  • Voir la page en français

    In brief

  • Teaching language : French
  • Teaching method : En présence
  • Code : NEGE2E


  • Know the characteristic criteria (security, stability ...) of an embedded or decentralized electrical network compared to a conventional distribution network.
  • Understand the main elements (storage ...) used in the design of such a network.
  • Propose different network architectures in relation to a given specification.
  • Be able to read a complete electrical diagram of a photovoltaic installation by being able to identify the various devices necessary as well as their function and sizing.


1. Security and reliability

  •  Related concepts (fault isolation, reconfiguration, backup network, ...)
  • Example of an aeronautical network


2. Mission Profile to be completed

  • Interest of sources hybridization to optimize their use
  • Using the Ragone plan in sizing storage units

3. Quality (AC and DC networks)

4. Stability (AC and DC networks)

  • Architecture and operation of AC power grids
  • Principles of frequency and voltage settings on networks (primary, secondary adjusments)
  • Power limitation of transportation lines
  • Instability related to filter - regulated system interactions

5. EMC issues
