Reduction power point tracking for standalone PV systems: Preliminary studies

This work proposes a Novel Reduction Power Point Tracking (RPPT) technique for Standalone PV systems. This technique enables PV System to dynamically adjust the PV power extracted to match the varying load demand in Standalone PV Systems. To understand the feasibility of the RPPT technique, preliminary studies are performed to understand operating points on both sides of the Maximum Power Point (MPP) on the PV characteristics curve for implementation. Using the Perturb and Observe (PO) embedded RPPT algorithm, simulation studies are performed under varying irradiance and varying load conditions to verify the tracking performance on both sides of MPP on the PV characteristics. This work helps in proliferation of the PV installations in developing nations and off grid systems, enhancing their utilization factor and also reduction in investment costs for supplementary energy sources accompanying the PV System.
