The requirements of power quality, public environment policy and expansion power demand are providing better opportunity to the microturbine (MTG) to be best microsources for improving the system stability, reliability and power quality. This paper presents modelling and control strategy of MTG system by using PQ controller and Droop control in islanded mode. The model developed in this work includes the individual components of prime mover like, compressor, heat exchanger, burner and turbine. The model of MTG system consists of microturbine, permanent magnet synchronous machine and power electronics interfacing circuit for generation and conversation from AC/DC/AC respectively and design of PQ controller including droop control with current and voltage loop and power loop. The simulations are carried out in islanded mode of the system to observe its behavior when supplying customer under variable load. It also incorporates modeling and simulation of microturbine with speed control, temperature control, and heat control, frequency control, voltage control and designing of filters in order to eradicate harmonics and suppress all kind of disturbance exist in network during transmission and distribution. The load following characteristics is observed and validated for this MTG-synchronous generator model in Matlab-Simulink environment with power system block.
