Decentralized and embedded electrical networks

• 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.
