Multi Functional PV Inverter with Low Voltage Ride Through and Constant Power Output

Project Code :TEMAPE205


The main objective of this project is to ensure a steady DC link voltage and remains connected to the grid during AC side low voltage and DC side low irradiation faults.


Renewable photovoltaic (PV) energy is a primary contributor to sustainable power generation in Microgrids. This paper presents a PV-inverter with low-voltage-ride-through (LVRT) and low-irradiation (LR) compensation to avoid grid flickers. The single-phase inverter rides through the voltage sags while injecting reactive power into the grid. The proposed control strategy ensures a steady DC-link voltage and remains connected to the grid during AC-side low voltage and DC-side low-irradiation faults. Unlike other PV inverters, the controller maintains the maximum-power-point-tracking (MPPT) in all conditions. LVRT, constant power output, and robust MPPT are the noticeable features of the proposed system. Frequency analysis, simulation validate the proposed control strategy in MATLAB/Simulink software.

Keywords: Microgrid, PV inverter, LVRT, constant power output, MPPT.
