Technico and Economic Optimization of the Injection of a Photovoltaic System on a Low Voltage Network

This paper investigates an experimental study of photovoltaic PV modules behavior (SM110-24) connected to the low-voltage grid (230 V / 50 Hz) with a three-phase inverter. In order to ensure maximum power point tracking (MPPT), The input voltage is delivered via a DC/DC converter that is controlled by the Fuzzy Logic Technical FLC to ensure maximum power MPPT. The control system of the setup is designed for the extraction of maximum power. The primary aim of this investigation is to synchronize the two sources namely PV-grid, using the Phase Locked Loop PLL command with the injection of an alternating current into the network whose aim is stabilizing the system and minimizing the cost of the energy consumed by the load. In this study, the authors have taken into account the real kWh price of the Algerian society of distribution of electricity (Sonelgaz) as the basis for their research. The simulation results obtained by utilizing the MATLAB software show that the proposed system exhibits high performance and flexibility, indicating its potential usefulness for practical applications in the future.
