摘要

提出基于相位补偿的虚拟同步机并网系统功率交互振荡抑制策略,通过分析有功输出和相位的关系,在原虚拟同步发电机（VSG）有功功率控制中建立前馈通道补偿输出相位,用于抑制多VSG系统在网侧频率波动时的功率交互振荡,提高系统的动态频率响应,且该方法既不受多VSG参数匹配条件的约束,也不影响系统稳态特性。文中给出关键参数的设计和稳定性分析,并根据硬件在环实验所得结果验证了所提策略的可行性。

Abstract

This paper proposes a power interaction oscillation suppression strategy for virtual synchronous generator grid-connected system based on phase compensation, by analyzing the relationship between active output and phase, and establishing a feed-forward channel to compensate the output phase in the original VSG active power control, which is used for suppressing power interaction oscillations in multi-VSG systems during the frequency fluctuation grid-side frequency fluctuations, and improving the dynamic frequency response of the system. In addition, the method is not constrained by the matching conditions of multiple VSG parameters, nor does it affect the steady-state characteristics of the system, and the design and stability analysis of key parameters are given. Finally, the feasibility of the proposed strategy is verified by results derived from hardware-in-the-loop experiments.
