Connection of distributed generation
Plan de protection des réseaux de distribution publique à moyenne tension

The protection schemes described so far apply to radial networks fed by a primary (T)HV/MV substation. The power flow is unidirectional, from the substation to the network. Today, we are witnessing a massive influx of decentralized generation connected to MV distribution networks, which can significantly alter the flow of power and have consequences for the protection plan.

This section merely gives an indication of the problems raised by the connection of this type of generation and a few possible solutions; for more details on the impact of this generation on the protection plan (protection mode and settings), see
