Abstract


This paper presents a closed loop grid current control of Solar PV-Wind hybrid source fed split inductor based DC-MLI. Renewable energy sources generate significant proportion of global energy demand and will be the focal point of power generation by the turn of a few decades. Hybrid systems integrate the standalone efficiencies of PV and Wind generation to complement and reinforce individual output. A Diode Clamped or Neutral Point Clamped three level inverter reduces switching stresses and is apt for medium voltage high power applications. Space Vector PWM control of inverter reduces harmonic distortion besides eliminating neutral point fluctuation, capacitor balancing problem and common mode voltage reduction. It provides switching states for the inverter based on location of a space vector using reference voltage from grid. Using closed loop control the total harmonic distortion in grid current was reduced. The simulation and experimental results of the proposed renewable hybrid system were verified using Matlab/Simulink and FPGA.
