Power System Simulator for Engineering (PSS/E) is a software tool used for electrical transmission networks. It is an integrated, interactive program for simulating, analyzing, and optimizing power system performance and provides probabilistic and dynamic modeling features. The software provides for transmission planning and engineers a tool for use in the design and operation of reliable networks. Since its introduction in 1976 it has become the most widely used commercial program of its type.
Wind turbines
With the increase in number and size of wind farms, PSS/E wind turbine models are used to simulate the effect on the electric grid.
