This paper deals with design and control of a connected wind energy generation system employing a Permanent Magnet Synchronous Generator (PMSG) driven by a variable speed wind turbine feeding single-phase loads. The proposed energy conversion system makes use of asymmetric NPC five level inverter. The dc terminal of the generator connected rectifier is tied to a boost converter for Maximum Power Point Tracking (MPPT) operation. An energy storage device is used to absorb the excess power generated from the wind turbine, and also to regulate the dc bus voltage. A pitch angle control is integrated to reduce the power generated from the wind when the battery SOC reaches 90%. The output voltage is tracked to its reference voltage in order to feed ac local loads. The proposed system is modeled and simulated using Simulink/Simpower of Matlab. The performance of the proposed system is presented, MPPT capability, dc and ac voltage regulation are also demonstrated.
