Title: Photovoltaic inverter control method based on a novel algorithm
Abstract: The key equipment of photovoltaic grid-connected system is photovoltaic grid-connected inverter; the output power quality is determined by the control method of inverter. Based on the model of a photovoltaic grid-connected inverter, this paper presents a new grid-connected inverter control algorithm that is iterative proportional integral algorithm, and derives an output expression and transfer function of grid-connected inverter. Control accuracy and speed of inverter were improved through real-time setting its optimal proportional-integral controller parameters; thereby the quality of the output current was ameliorated. Simulation and experimental results show that this method has a high practical value.
