AI Technical Summary

Technical Problem

Existing technologies lack a global maximum power point tracking (MPPT) algorithm in photovoltaic module power generation systems, which makes it impossible to effectively track the maximum power point under partial shading conditions. Furthermore, photovoltaic optimizers cannot perform a global MPPT search for individual modules under string MPPT, affecting power generation efficiency and system stability.

Method used

The system employs a global MPPT function to launch the analysis module, management module, evaluation module, and early warning terminal. By analyzing the irradiance and module data of photovoltaic modules, it selects the best optimizer, performs a global MPPT scan, and identifies multi-peak phenomena in real time, thereby achieving intelligent power tracking and fault early warning for photovoltaic modules.

Benefits of technology

It has enabled high-efficiency power generation of photovoltaic modules, timely detection and resolution of multi-peak issues, improved power generation efficiency and system stability, and ensured the maximum utilization and security of energy.
