Impact on system safety
Raccordement de la production décentralisée aux réseaux de distribution

The problem for the Transmission System Operator (TSO) is twofold. It must at all times :

• make sure there is equality between production and consumption;

• ensure that the power transited on network facilities (lines and transformers) does not exceed their capacity. In other words: managing congestion.

This problem quickly becomes complex:

• by taking into account operating contingencies affecting network elements or generation plants, consumption levels ;

• by the need to control the safe operation of the power system – maintaining the voltage, frequency and stability of generation units.

Added to this is the need to maintain the network,...
