Abstract: The integration of floating photovoltaic systems in electrical distribution networks enhances efficiency and sustainability in rural areas. This research analyses the impact of floating photovoltaic generation on electrical distribution systems in rural Ecuador, specifically at the La Esperanza hydroelectric dam. To achieve this, an artificial neural network model is developed to identify optimal outcomes. The objective function and constraints within the ANN model determine the optimal FPV capacity and placement to maximize active power injection at each node and minimise power losses. To simulate various scenarios and assess the effectiveness of FPV integration, a power flow model using the forward and backward sweep method was employed. The results for the electrical distribution systems indicate increased energy efficiency, improved voltage profiles, and reduced losses. Optimal FPV integration decreases grid dependency by up to 60 %, reduces losses by up to 20.2 %, and enhances the voltage profile by up to 5 %.
