According to the invention, power matching in an electricity grid (N) is carried out by regulation of a storage power station (S) which is operated in the grid. In the event of changes in the power available or in the power consumption in the grid, the power consumption of the power consuming machine (V) in the storage power station is adapted so as to maintain equilibrium between the total power generation and the total power consumption. Power matching by regulation of the power load can be carried out around one order of magnitude more quickly than power matching by regulation of power generating machines (G1, G2, G3, GS) which act on the grid, and saves alternating thermal loads in the power stations.

Selon l'invention, l'adaptation de puissance dans un réseau électrique (N) se fait par régulation d'une centrale d'accumulation (S) exploitée dans le réseau. Lors de variations de l'offre de puissance ou de la consommation de puissance dans le réseau, l'absorption de puissance de la machine de travail (V) de la centrale d'accumulation est adaptée de sorte qu'un équilibre subsiste entre la production de puissance totale et la consommation de puissance totale. L'adaptation de puissance par régulation du consommateur de puissance peut se faire plus rapidement environ d'un ordre de grandeur qu'une adaptation de puissance par régulation de machine motrice (G1, G2, G3, GS) agissant sur le réseau et permet d'éviter des charges alternatives thermiques des centrales.
