Closed Loop PI Control of PV Tied Grid System with Multi-Carrier PWM Based Modular 5-Level Converter
Keywords:PV module, Modular 5-level Converter, Half bridge sub-module, Multi-carrier PWM technique, PI controller, Grid synchronization
As the contribution of PV in the area of power production is significantly high in the recent period, it is preferred in various applications. In this present study, a control scheme is proposed for tracking the maximum power from each individual PV module. Due to the changes in temperature, the output of PV gets oscillated and fails to provide constant DC voltage. A Modular 5-level converter (M5LC) is employed, which converts the fluctuating voltage of PV module into a constant value. This DC-DC converter is controlled by the aid of multi-carrier PWM technique. By implementing PI controller, the reference signal is generated and analogized with the carrier signals of MCPWM technique for generating the gating sequence to control the M5LC. The converter’s DC output voltage is fed to the VSI, which converts the DC into AC voltage. The gating pulses of the inverter is generated with help of PI controller, through which the grid synchronization is achieved and the THD is minimized. The proposed control method is validated through MATLAB simulation.
