Abstract

This paper proposes a novel maximum power point tracking (MPPT) algorithm that is combined with the advanced three-point weight comparison method (ATPWC) and MPPT limit detect (LD) mechanism and applied to a single stage standalone solar photovoltaic system. The boost converter is connected to the inverter and filter to deliver single-phase AC 110 VAC/60 Hz to the load. The MPPT LD detects when the system does not need MPPT based on the solar photovoltaic module's (SPV module) R_pv and load R_o. In addition, this study performs actual measurements for validation, in which the proposed algorithm is used in the built single-stage standalone solar photovoltaic system and compared with the ATPWC, three-point weight comparison method (TPWC), and conventional perturbation and observation (P&O) for MPPT efficiency. The result shows that the proposed algorithm is better than the other three algorithms. When the system is under a heavy load (R_pv > R_o), the overall system efficiency is 80%, while the efficiency under a non-heavy load (R_pv ≤ R_o) is 99%.
