Abstract

An energy supply network includes at least one power station plant, at least one energy supplier, at least one energy infeed node, a number of energy distribution nodes and a number of consumers, which are supplied with electrical energy via the energy distribution nodes. At least some of the energy distribution nodes each include a power measuring instrument, via which the summated electrical power taken by all those consumers which are supplied with electrical energy via the respective energy distribution node, can be established. Further, a method makes use of previous and present consumption data in order to forecast a power demand as accurately as possible and to arrange for an appropriate feeding-in of electrical energy into the infeed node by the power station plant.
