    Abstract

    As electric power develops, stable distribution of output power has become a key issue, and more and more power distribution strategies have been proposed. However, most of them are single distribution strategies with large errors and low credibility, which makes it difficult to maintain the stability of motor output distribution power in the actual situation. Therefore, by characteristics of adaptive virtual impedance to reduce small signals influence in the circuit and parallel power stability of virtual synchronous machine virtual synchronous generator control strategy, this research establishes a parallel power model of virtual synchronous generator, selects the changes of voltage and current as the measurement standard of the system, and sets up simulation experiments to determine whether to add adaptive virtual impedance to design a control strategy that can stably distribute output power. Results showed that it can keep output ratio of active power and reactive power within range of 2:1, and voltage difference at the output terminal is 0, and the current is 0.8A, which meets the requirements of circulating current. In a word, the control strategy of virtual synchronous generator designed in this research has high accuracy and strong stability. Compared with previous control strategies, the control strategy of parallel power distribution can ensure the stability of output power in the actual situation. This achievement has certain application prospects in the field of motor power distribution.
