New Maximum Power Point Tracker for fast changing environmental conditions

摘要

This work presents a high performance Maximum Power Point Tracker (MPPT) optimized for fast changing conditions on the PV panels. This approach adjusts automatically a step size to the solar array operating point, thus improving the MPPT (Maximum Peak Power Tracking) speed and accuracy compared with the conventional method with a fixed step size when the irradiance or temperature are changing rapidly, and lower oscillations around the MPP in steady-state conditions. The simulations results show that the proposed dP-P&O MPPT provides a effectiveness of this approach.
