Abstract
AbstractIn the inverter parallel system, due to the uncertainty of the working environment, the output voltage cannot meet the requirements, and the power distribution accuracy by the traditional droop control method is low. To increase the control accuracy of the output voltage of the inverter parallel system and improve the power distribution accuracy between parallel modules, this paper proposes a parallel inverter control method based on adaptive parameters. This method is improved on the basis of traditional P‐V droop control, and an adaptive parameter control method is implemented by the Lyapunov function, which can effectively improve the control accuracy of the output voltage and ensure that the output voltage remains within a certain constraint range under any load conditions. In order to further improve the output voltage control accuracy, the adaptive parameter control method is adopted. The parameter optimization strategy was deduced, and the steady‐state and dynamic control performances were significantly improved. Simulation and experimental results verify the effectiveness of the proposed control method.
