Research on three-phase parallel photovoltaic inverter based on improved virtual oscillator control

As the field of power electronics continues to evolve, new energy generation technologies are gaining increasing attention. This has made the study of inverter control strategies more crucial than ever. Traditional control strategies for inverters operating in parallel have encountered limitations due to the need for output power calculation, which hampers dynamic performance. This paper introduces an inverter control strategy based on improved virtual oscillator control that enables autonomous parallel operation of inverters. Compared to conventional inverter control methods, this strategy offers rapid dynamic response and strong disturbance rejection capabilities. Through parallel simulation of improved virtual oscillator control inverter, the proposed control strategy has been demonstrated to provide excellent dynamic performance and reliability under parallel operating conditions.
