PAT: A Power Analysis Toolbox for MATLAB/Simulink

A power system simulation environment in MATLAB/Simulink is presented in this paper. The developed Power Analysis Toolbox (PAT) is a very flexible and modular tool for load flow, transient and small signal analysis of electric power systems. Standard power system component models and a wide range of FACTS devices are included. Its data structure and block library have been tested to confirm its applicability to small-to medium-sized power systems. Its advantages over an existing commercial package are given.
