==Load flow calculation==

The load-flow calculation<ref>{{Cite journal|last=J.

Using network topology, transmission line parameters, transformer parameters, generator ___location and limits, and load ___location and compensation, the load-flow calculation can provide voltage magnitudes and angles for all nodes and loading of network components, such as cables and transformers. With this information, compliance to operating limitations such as those stipulated by voltage ranges and maximum loads, can be examined. This is, for example, important for determining the transmission capacity of underground cables, where the influence of cable bundling on the load capability of each cable has to be taken also into account.
