Method for distributing electrical energy in a power network with a number of distribution network cells

The power is fed from generator units (8-1-1-8-n-m) to distribution network cells (4-1,4-2). The calculation units (12-1-12-n) are provided to determine preliminary overall price curve for required electric power for preset time based on predicted market price curves. An expected load demand curve is determined from preliminary overall price curve. A total demand curve determined from expected load demand curve is used for determining cumulative total demand curve for required power in distribution network cell if predicted energy flow in network cell exceeds preset value.
