Abstract

The main aim of this paper is to enhance the power quality problems in a micro grid system. A flexible ac distribution system is presented in this paper for improving the reliability and power quality of the distributed system to which the microgrid is connected. In order to improve the system computational time and response a new control algorithm is designed for controlling the Facts devices. The Fuzzy Controller is also employed in this paper for frequency tracking and for extracting the harmonic spectra of the grid voltages and load currents in a micro grid. The design concept is tested in different cases using MATLAB/SIMULINK.

Abstract

Injection of power generated by the wind turbine system into an electric grid mainly effects the power quality. The performance of this wind turbine and its power quality is determined on the basis of its measurement of power ratings as per Institute of Electrical and Electronics Engineers (IEEE) standards. The influence of the wind turbine in the grid system concerning the power quality measurements are the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation. To mitigate the power quality problems this paper proposes the shunt compensator techniques. Here, the proposed system is verified experimentally using both Static Synchronous Compensator (STATCOM) and Thyristor Switched Capacitor (TSC) compensators. This control schemes for grid connected wind energy system is simulated using Matlab/Simulink.
