Decentralized and embedded electrical networks
Objectives
- 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.
