Modified Maximum Power Extraction technique for rapidly changing NUI and dynamic loads

In this paper, a modified algorithm for global maximum power extraction is demonstrated using Solar PhotoVoltaic array with distributed sensor network. The SPV array exhibits multiple power peaks during Non-Uniform Illumination (NUI) conditions. The algorithm demonstrated in this paper traces the global power peak by instantaneously predicting the power using multiple sensors data while also offering flexibility for varying load characteristics. Different technology SPV modules are studied to validate the importance of technology in predicting global maximum power point. Simulation studies are carried out and an analysis is presented to validate the effectiveness of the algorithm. The proposed algorithm is also verified by simulation models at different NUI scenarios with different load conditions.
