Abstract
This paper presents a contribution to the modeling and optimization of a grid-connected photovoltaic (PV) power generation system. A comparative study was conducted through simulations using PVsyst software, yielding promising results. Additionally, an experimental investigation involved positioning a flat mirror 10 meters from a PV panel to enhance the incident irradiance, thereby increasing the available energy for storage. The experiment demonstrated an irradiance boost of 15.2%, highlighting the potential of this approach for the future photovoltaic plant installation at Denis Sassou Nguesso University. The simulation results enabled optimal sizing of the PV system tailored to the site conditions. PVsyst also facilitated the simulation of current-voltage (I V) and power-voltage (P V) characteristics under varying solar irradiance and ambient temperature, which are critical parameters for assessing PV generator performance in different climatic scenarios. Although this work does not claim novelty in PV system modeling and optimization, the integration of reflective surfaces in a grid-connected configuration represents an innovative contribution. This approach offers promising prospects for enhancing the energy yield of PV installations, especially in regions with high solar irradiance variability. The electrical engineering research community is encouraged to further investigate and validate this innovative method to advance its practical application.
