Investigating the Intelligent MPPT Controller for a Stand-alone PV and Wind Hybrid System

The system consists of PV system, wind energy conversion system (WECS) and battery and intelligent MPPT controller. The PV/wind hybrid system can give fluctuating output that makes the system unstable, a battery is connected to the system to reduce the fluctuations in output voltage. To get the stable response for the system intelligent MPPT controller is used. The intelligent MPPT controller uses artificial neural network to extract maximum power point. PV and wind energy conversion system consists of MPPT algorithms. An Artificial Neural Network (ANN) based MPPT is proposed to get the maximum power from the system. The DC-DC boost converter is connected to the DC link. The output signal from MPPT controller is used as duty cycle of the DC-DC boost converter. The PV and wind block with intelligent MPPT controller are modeled separately in MATLAB/Simulink before connecting them together to build a hybrid system. The performance analysis is done under different wind speeds, solar irradiance and temperature in MATLAB/Simulink.
