Power System Simulator for Engineering (PSS®E—often written as PSS/E) is a software tool used by power system engineers to simulate
electrical power transmission networks in steady-state conditions as well as over timescales of a few seconds to tens of seconds.
Since its introduction in 1976, it has evolved from a simple
command-line interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and pro ...
, to an integrated, interactive program for simulating, analyzing, and optimizing power system performance, and it can provide probabilistic and dynamic modeling features.
