针对虚拟同步发电机（virtual synchronous generator，VSG）输出的有功、无功间存在耦合，影响其最终电压和频率调节能力，严重情况下将引发系统失稳的问题，提出一种基于对角阵补偿矩阵的解耦策略，实现虚拟同步发电机的功率静态解耦。针对VSG的功率耦合问题，采用串联对角阵补偿矩阵实现VSG的静态功率解耦；在考虑VSG运行工作点变动的情况下，采用基于功角估算的对角阵补偿矩阵直接解耦法进一步优化VSG的动态功率解耦特性。最后通过仿真对所提方法的有效性进行了验证。
Abstract：Due to the coupling between the active and reactive power output of VSG affects its final voltage and frequency regulation ability, and in severe cases, can cause system instability, this article adopts a decoupling strategy based on diagonal matrix compensation matrix to achieve static power decoupling of VSG, and introduces an optimized decoupling scheme based on power angle estimation to address the drawback of decoupling performance being affected by the operating point of the system. Finally, the effectiveness of the relevant control is verified through simulation.
