Maximum power point tracking for a photovoltaic power system

Abstract

This dissertation proposes a novel maximum power point tracking (MPPT) algorithm that works optimally for a photovoltaic system under fast changing temperature and irradiation conditions. The new approach can effectively improve the tracking speed and accuracy simultaneously, which is the contradiction in conventional methods such as P&O or INC. This is particularly important for photovoltaic systems that frequently experience rapidly changing environmental conditions.
