Abstract
Wind generation is being increasingly connected at distribution level due to increasing load demand. Permanent magnet synchronous generator (PMSG) is connected to the wind turbine directly. Through the full power control of AC-DC-AC converters, the electrical power is then connected to the power grid. The power conversion circuits are made up of generator-side three phase diode rectifiers, b oost converter and the grid-side three bridge s and four wire inverter s . A boost converter is controlled through an intelligence controller to maintained DC power constant despite of Variable output of PMSG, t he grid-connected operation is constructed using the hysteresis current control method. The inverter is controlled to perform following function 1) power converter to inject power generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current . The model is implemented in MATLAB/ Simulink using sim power system.
