Mitigation Of Voltage Fluctuations Due To 3P Oscillations Of Wind Farm Using Series Controller

Rapid increase in demand for power, depletion of conventional energy sources and their adverse effects on environment is making power engineers to look for alternatives for power generation. Power generation through wind gained more popularity across the world due to technology advancements and low installation costs compared to solar and other sources of renewable energy. Grid integration of wind turbines has negative impact on grid operation due to random nature of wind, wind shear and tower shadow effects. Thus, the wind turbines are fluctuating power sources that influence power quality in distribution system. This paper presents a series controller for blocking these disturbances and maintaining the power quality within the acceptable limits defined by industry standards. The simulation results, carried out by using MATLAB/SIMULINK show the impact of these disturbances on the grid. The proposed series controller is found to be an effective tool in blocking disturbances at the point of common coupling and thereby maintaining the power quality.
