    Design and implementation of three-level inverter for grid-tied PV systems
    (IEEE, 2017) Ayachi Amor, Nourdine; Ayachi Amor, Nourdine; Kheldoun, Aissa; Metidji, Brahim
    High quality voltage and current are required when PV generator is connected to grid utility. To this, multilevel inverters are very desirable to be used as connection interface. To keep the cost of the whole system as low as possible, a cost-effective control device using STM32F4 discovery board is employed to control three-level inverter that can be used in grid-tied PV system. The paper develops and implements the control strategy of simplified space vector pulse width modulation (SVPWM) algorithm using Matlab/Simulink software. Obtained experimental results depict the powerfulness of used card as well as the high quality of the delivered power

    Grid Connected Solar PV System: Modeling, Simulation and Experimental Tests
    (Elsevier, 2016) Kesraoui, Mohamed; Lazizi, Aldjia; Chaib, Ahmed
    In this paper a solar PV system is modeled, simulated and experimentally tested. Mathematical and electrical models have first been presented. A theoretical background which introduces the topic has been presented. The system's different components have also been described. Then a simulation work of the current voltage (I-V) characteristics and efficiency by using MATLAB/IMULINK has been performed. Finally a PV system installed in the Institute of energy systems and electrical drives at the Technical University of Vienna has been tested. Many disturbances and cases like blackout, load disconnection and islanded system have been investigated. In this mainly experimental work, three test situations have been performed and the corresponding measurements have been recorded. Results that have been obtained showed that the grid connected PV system responds adequately to all the applied disturbances
