摘要

针对常规基于一阶环节虚拟惯性的虚拟同步发电机(VSG)并网运行时输出功率控制动、稳态特性存在矛盾的问题，提出了基于微分补偿环节虚拟惯性的VSG控制策略，该控制策略在常规VSG 控制结构前向通道加入微分补偿环节，从而在保证输出功率稳态控制精度的同时，加快了动态功率响应速度，增加了系统阻尼，有效减小了储能单元动态过程的功率冲击。仿真和实验验证了所提方案的有效性。

Abstract

Aiming at the regulation contradictions between output active power steady-state and dynamic characteristics when the conventional virtual synchronous generator(VSG)based on first-order link virtual inertia is connected to the utility grid

a VSG control strategy based on differential compensation virtual inertia is proposed. Through the incorporation of a differential link in the forward channel of conventional VSG control structure

the control strategy accelerates the power response speed

increases the damping of the system

and reduces the power impact on the energy storage unit of VSG during the dynamic process

while ensuring the maintenance of the output active power steady-state control precision. Simulation and experiments have validated the effectiveness of the proposed strategy.
