Abstract: This study presents the simulation and design of a grid-connected single-phase photovoltaic (PV) system using PSCAD/EMTDC, specifically targeting the energy needs of Tanzania. This project explores the potential of solar energy as a sustainable solution to meet the growing energy demands in Tanzania, where energy access remains limited, with only 38% of the population having access to it. In this study, a 12-kW solar PV system was designed, incorporating MPPT controllers, DC-DC boost converters, and grid connection strategies. The simulation results show the effectiveness of the proposed system in maintaining power quality and optimising maximum power point tracking (MPPT) under varying solar irradiance and temperature conditions. The model meets international grid standards and demonstrates the feasibility of solar energy as a viable solution to the energy challenges in Tanzania.
