基于暂态阻尼提升的VSG并联系统低频功率振荡分散式协调抑制策略
Decentralized Coordinated Suppression Strategy for Low-frequency Power Oscillation in VSG Parallel Systems Based on Transient Damping Enhancement
摘要
Abstract
The virtual synchronous generator(VSG)simulates the characteristics of synchronous generators to provide inertia and damping,but inevitably introduces the rotor oscillation characteristics of synchronous generator.Especially in VSG parallel operation systems,when the system is disturbed,it is prone to cause power oscillation problems,which may even damage power electronic equipment.To address this issue,based on state feedback and pole-placement theory,a power oscillation decentralized coordinated suppression strategy for VSG parallel systems based on transient damping enhancement is proposed.By constructing a combination of angular frequency high-frequency component compensation and electromagnetic power high-frequency component compensation,the transient damping of the system is improved,and power oscillation is suppressed without affecting the system steady-state characteristics.Then,the stability of the proposed control strategy is demonstrated by constructing a Lyapunov function.Finally,the effectiveness of the proposed method is verified through simulation.关键词
