Photovoltaic Grid-Connected System Model

For my graduation project, I conducted research on the modeling of photovoltaic grid-connected systems and compiled relevant reference materials. The project began with extensive literature collection to understand the principles and operational mechanisms of photovoltaic power generation systems. This was followed by the design and development of the system model, which involved component-level modeling (such as photovoltaic cells and arrays), inverter modeling for DC-AC conversion, and integration of the entire system. To ensure model accuracy and reliability, I performed numerous simulations and tests, analyzing and interpreting the results to validate the system's performance. The implementation included coding key algorithms for maximum power point tracking (MPPT) and grid synchronization. Finally, I organized all reference materials and presented my research findings through a comprehensive experimental report to both professors and peers.
