Modelagem, análise e controle de um sistema fotovoltaico para geração distribuída empregando conversores estáticos como forma de controlar a potência injetada na rede.

Abstract

Photovoltaic solar energy presents itself as a reality capable of making a significant contribution to the world energy matrix. However, the efficiency of the solutions for the use of photovoltaic solar energy is still low, in this way, the boost converter must guarantee that the system provides the maximum possible power and for this it is necessary to study and use maximum extraction techniques. panel power. For the conversion from a continuous source to an alternating source, an inverter is necessary to control the power from the DC bus to the grid using control loops and coordinate change. For this it is necessary to use a PLL. In order for the converter to get off the ground and be approved, it must have a low THD. In order to have a low THD, a lowpass filter capable of attenuating unwanted harmonic components is necessary.
