Integration of wind generation system in low voltage distribution system

The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations. Few options to name in distributed energy resources are solar, photo voltaic, wind turbines. Wind generation has been commercially available for many years and the main push has been in large wind farms where wind turbines from 700 kW to 1.5 MW are available and in use, though one of the challenges in injecting wind power into grid is power quality. Role of a Distribution Static Compensator (DSTATCOM) in effective operation of grid along with Wind Energy Conversion System (WECS) is analysed in details in this study. This also covers the analysis of key parameters being influenced by using WECS like active/reactive power, harmonics and voltage at the point of common coupling. With every step increase in speed of wind turbine in this scheme, the active power injected by the wind source increases and hence reduces the power requirement from the grid proportionally. Simultaneously, DSTATCOM helps in balancing the load unbalance and supplying the reactive power required by wind generator, hence improving the grid power quality. The simulation has been done using MATLAB/SIMULINK in power system block-set.
