Abstract
The development, operational control and
evaluation of the events in the power system necessitate
different network calculation methods. A stationary grid model is used
for load distribution and contingency analysis. The classic loadflow
algorithm is an iterative solution for equation system of thousands of
variables. For the efficient computation of networks containing huge number
of nodes and branches some acceleration and simplification algorithms
are used, too (decoupled and DC
loadflow).
The emerging structures as the large nonmeshed radial networks, microgrids,
power quality islands open new frontiers instead of the exhaustive numbercrunching
techniques. The tasks can be rephrased, and the application of several
intelligent computation methods can be relevant, as the artificial neural
networks and some optimization techniques. This paper introduces the on
and offline tasks of the network calculations, the existing methods and
the novel techniques.
