Performance Analysis and Comparison of Hybrid Interconnections Photovoltaic System Architecture Under Partial Shading

The efficiency of a Photovoltaic (PV) system is heavily influenced by environmental factors including solar irradiance, temperature, dust accumulation, bird droppings, PV array interconnection, and shading patterns. Partial shading often results in nonuniform irradiance across PV arrays, causing power mismatches between modules and giving rise to multiple maximum power points (MPPs) within the system's power characteristic. In addressing these challenges and aiming to boost power output under such conditions, diverse PV array interconnection and reconfiguration schemes like series-parallel (SP), honeycomb (HC), Bridge linked (BL), Total cross tied (TCT), and combinations thereof are employed.This study delves into the analysis and comparison of the performance of these interconnections in the context of various partial shading conditions, with a specific focus on module-level mismatches. Additionally, the paper explores the potential for power enhancement in PV systems by utilizing submodule-level mismatch mitigation PV array interconnections. The primary objective is to assess the performance of PV array interconnections at the submodule level across different Partial Shading Conditions (PSCs). Key performance parameters, including maximum power generation (P GM ), mismatch power loss (MLP), and fill factor (FF), are employed for comparisons with module-level interconnections.
