A Study of Maximum Power Point Tracking in Novel Small-Scale Photovoltaic LED Lighting Systems

摘要

While most of the current maximum power point tracking (MPPT) algorithms for large photovoltaic systems are complicated and inefficient, this paper proposes a novel method of MPPT specially used in small-scale photovoltaic LED lighting systems. The proposed algorithm is based on the improved research on the characteristics of the PV array in novel lighting systems. The proposed method in the special system keeps the operating point on two fixed values which have been calculated based on the research of PV array. It is investigated and confirmed by the simulation that the proposed MPPT method in small-scale photovoltaic LED lighting systems is simple and efficient.
