Network Representation

A model is always an approximation of the real world. An important consideration in distribution system modeling is which components will be represented and what approximations are made in representing the components.

The level of representation may be limited by model constraints, cost, time, information availability, or personal preference.

With the increasing power of computers and availability of more powerful simulation models, the general trend is towards more detailed representation.
