Electrical energy has to be generated during the time it is needed. Th
is is in contrast to economic efficiency in power generation since the
best operating point for a power plant is a constant power generation
at its best economical rating. The presented approach shows a way to
schedule loads that do some energy storage to consume electrical power
when it is available at lower generation costs. An evolutionary algor
ithm is evaluated, which computes the optimal operation times of the m
entioned loads. Since the evolutionary strategies (ES) themselves do n
ot consider special cases, a knowledge base is integrated into the alg
orithm. The resulting approach allows a more efficient application of
telecontrol system for load management.
