| description | The invention discloses a VSG control method based on a Lyapunov second method, and discloses a system with the VSG control method based on the Lyapunov second method, and the VSG control method based on the Lyapunov second method comprises the steps: continuously obtaining the angular velocity and calculating the difference value between the VSG angular velocity and the equivalent angular velocity of a power grid by using the adjustable characteristic of VSG parameters; and then changing an iterative value in the operation according to the magnitude and the change degree of the angular velocity difference value, and changing the angular velocity in the VSG, thereby enabling the system to reach a stable equilibrium point more quickly.
本发明公开了一种基于Lyapunov第二法的VSG控制方法，并公开了具有基于Lyapunov第二法的VSG控制方法的系统，其中基于Lyapunov第二法的VSG控制方法包括利用VSG参数可调整的特性，不断获取角速度并计算VSG角速度及电网等效角速度的差值，然后依据角速度差值的大小和变化程度来改变运算中的迭代值，并改变VSG中的角速度，从而更快速的使系统达到稳定平衡点。 |
