Hybrid MPPT control method

Abstract

Conventional maximum power point tracking (MPPT) algorithms in photovoltaic power generation systems usually have difficulty in balancing the tracking rate and accuracy. To solve this issue, a hybrid MPPT control method is proposed in this paper. By injecting a high-frequency sinusoidal ripple into the basic duty cycle to produce a sinusoidal fluctuation of the PV output power, and the phase difference between the duty cycle and the power fluctuations provides a reference for tracking the maximum power point (MPP) of the PV power system. At the same time, the proposed hybrid MPPT control method can automatically update the MPP by detecting variations in environmental conditions under a steady operation state. Finally, an experimental platform is built for validation. Experimental results verify that the proposed method has good dynamic and steady-state performances for the MPPT of the PV power generation system.
