Utility restructuring, technology evolution,

public environmental policy, and expanding power

demand are providing the opportunity for microturbines

to become important energy resources. In order to

investigate the ability of microturbine units in

distribution systems, new simulation tools are needed.

This paper presents a dynamic models for microturbines.

For the purpose of modeling initialy a dynamic model

for each component in the system, including gas turbine,

permanent magnet generator, DC bridge rectifier and

power inverter is developed and after this stage the

model is implemented in a simulation software. In this

research the simulation tool is Matlab/Simulink. Also the

systems stand-alone dynamic performances is analyzed

and evaluated.
