Abstract :This study conducts a detailed performance comparison between two large-scale photovoltaic (PV) power plants, each with an installed capacity of 1 MW. One system follows a conventional PV configuration, while the other incorporates a battery energy storage system (BESS) for enhanced functionality. The BESS-integrated system employs a peak-shaving strategy, aiming to store excess energy generated beyond 1 MW during daytime hours. The primary goals are to extend the PV system’s energy supply into peak demand periods following sunset and to improve responsiveness to energy demand fluctuations. Both configurations were independently modeled using the same simulation environment, with a focus solely on technical performance, excluding economic considerations. Simulation results reveal that the BESS-enhanced system delivers an additional 153.18 MWh annually to the grid and achieves a 4.8% improvement in performance ratio. These findings highlight the technical benefits of BESS integration in PV systems, particularly its contribution to improving energy continuity. The study offers valuable insights for system designers, investors, and researchers regarding the implementation of BESS in solar power applications.
