The method according to the invention is based on a configuration model of a
part of an electrical power distribution network, describing a totality of possible
configurations of appliances. The configuration model is used to systematically
produce (2) all the possible configurations which satisfy a predetermined
set of functional requirements, in which case each possible configuration may have
at least one associated characteristic value, and a solution configuration is defined
which optimizes this characteristic value. It is thus possible to produce an optimum
configuration automatically, without any need for expert knowledge about the appliances
used in the configuration. In one preferred embodiment of the invention, a simulation
model for simulation of a technical response of the solution configuration is produced
automatically (3). It is thus possible to test one or more solution configurations
by simulations (4), without any need for expert knowledge about the characteristics
and simulation models of the appliances used in the solution configuration.
