This study aims to apply the ripple correlation current (RCC) approach, which is an MPPT search algorithm used in photovoltaic systems. To extract the maximum power, a wind conversion structure based on a permanent magnet synchronous generator (PMSG), a three-phase rectifier and a boost converter is used. The choice of this structure is justified by the reliability, simplicity of implementation and...
The present work describes the analysis, modeling and control of a Boost-Buck power inverter used as a DC-DC and DC-AC power conditioning stage for autonomous photovoltaic (PV) systems. To maximize the steady-state input-output energy transfer ratio a backstepping controller is designed to produce balanced three phase voltage, extract and transfer a maximum Power extracted from photovoltaic generator...
Power point tracker algorithms play an important role in the optimization of the power and the efficiency of a photovoltaic generator. This work presents a comparative study of performance Maximum Power Point Tracker (MPPT) algorithms for fast changing conditions on the PV panels. We made the comparison between algorithms currently implemented for the power optimization of photovolatic system. These...
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,...
In this paper, we study a system consisting of a photovoltaic (PV) array panel, dc-to-dc switching converter and a battery. A backstepping PWM controller is developed to maximize the power of the solar generating system. The controller tracks a desired array voltage, designed online by using MPPT algorithm, by varying the duty cycle of the switching converter. The stability of the control algorithm...
