چکیده
The microturbine generation (MTG) system are becoming the popular source of distributed generation (DG) due to their fuel flexibility, reliability and power quality. The MTG system is a complicated thermodynamic electromechanical system with high speed of rotation, frequency conversion and its control strategy. In spite of several techniques to control high speed of microturbine is not accurate and reliable due to their anti-interference problem. This paper presents a fuzzy logic controlled MTG system for grid connected and islanded mode of operation. The development of fuzzy logic based speed governor includes input and output membership function with their respective members. The load variation on MTG system is performed using conventional PI controller and fuzzy logic controller are implemented in Matlab/Simulink and their results are compared with each other. The simulation result of MTG system shows the performance improvement of fuzzy logic governor over a conventional governor.

The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....

متن کاملA Fuzzy Based Under-Frequency Load Shedding Scheme for Islanded Distribution Network Connected with DG
The frequency of power system is very sensitive to load changing when operating in islanded mode. This may causes overloading or loss of generation cases. Under-Frequency Load Shedding (UFLS) Scheme is commonly applied to stabilize the frequency during these cases. Conventional UFLS scheme operates successfully in interconnected grid system and may not work well when applied to DG based system ...
