ABSTRACT
Power system software can be grouped in many different ways, e.g., functionality, computer platform, etc., but
here it is grouped by end user. There are four major groups of end users for the software:
Major utilities
Small utilities and industry consumers of electricity
Consultants
Universities
Large comprehensive program packages are required by utilities. They are complex, with many different
functions and must have very easy input/output (IO). They serve the needs of a single electrical system and
may be tailor-made for the customer. They can be integrated with the electrical system using supervisory
control and data acquisition (SCADA). It is not within the scope of this chapter to discuss the merits of these
programs. Suffice to say that the component programs used in these packages usually have the same generic/
development roots as the programs used by the other three end-user groups.
