为实现对逆变器在离网状态下不平衡电压的控制 Control Method of VSG

代码说明：

  为实现对逆变器在离网状态下不平衡电压的控制，通过 d-q坐标系下电感电压正负序解耦控制，同时利用VSG能够为电网提供惯性的特点，使逆变器交流侧实现三相电压平衡。改善了离网不平衡状态下负序电压对电网的影响，从而抑制了逆变器输出有功功率的波动，提高了系统的稳定性。通过仿真实验证明所提方法的有效性。(In order to realize the control of the unbalanced voltage of the inverter in the off network state, the inductance voltage and positive and negative sequence decoupling control in the d-q coordinate system, and the characteristics of the VSG can provide the inertia of the power grid, make the inverter AC side realize the three-phase voltage balance. The influence of negative sequence voltage on the power grid is improved under the condition of off balance network, thus suppressing the fluctuation of the output active power of the inverter and improving the stability of the system. The validity of the proposed method is proved by the simulation experiment)
