Enhancement of Micro Grid Power Quality with cascaded Voltage-Current control

B Gayathri, M Nagarjuna

Abstract


Microgrid (MG) is the indispensable infrastructure of now smart grid, however, variation and intermittence caused from unstable micro-sources and nonlinear loads will execute considerable impacts on normal operation of the MG. The micro-grid is paradigm of the first-time, examination in this area is rising incessantly. The wind energy generation, utilization and its grid penetration in electrical grid are growing world-wide. The wind produced power is continuously changing due to its time varying nature and causing stability problem. Unified Power Flow Control (UPFC) is used to control the power flow in the transmission system by controlling the impedance, voltage magnitude and point approach.  Injection of wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro technical Commission standard, IEC-61400-21. 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. The paper study demonstrates the power quality problem due to installation of wind turbine with the grid. In this proposed scheme STATIC COMPENSATOR (STATCOM) is connected at a point of common coupling to mitigate the power quality issues. The STATCOM control scheme for the grid connected wind energy generation system is simulated using MATLAB/SIMULINK in power system block set.
