| 摘要: |
| 为了解决在有功功率指令、电网频率2种扰动情况下储能虚拟同步机(VSG)并网有功难以兼顾良好的动态特性和稳态性能的问题，提出了一种基于有功分数阶微分校正的VSG(AFDC-VSG)并网有功响应优化控制策略。分别建立典型VSG、AFDC-VSG这2种控制策略的并网有功闭环小信号模型，并给出相应的参数设计过程。利用MATLAB/Simulink仿真软件对比分析不同控制策略在2种扰动下储能VSG的并网有功响应特性，并建立储能VSG并网系统的实验平台。仿真和实验结果共同验证了所提AFDC-VSG策略在优化储能VSG并网有功响应性能方面的有效性与优越性。 |

| Abstract: |
| In order to solve the problem that the grid-connected active power of energy storage virtual synchronous generator(VSG) is difficult to take into account the good dynamic characteristics and steady-state performance under the disturbances of active power command and power grid frequency, a grid-connected active power response optimization control strategy of active power fractional differential correction-based VSG(AFDC-VSG) is proposed. The grid-connected active power closed-loop small-signal models of typical VSG and AFDC-VSG control strategies are established respectively, and the corresponding parameter design processes are given. MATLAB/Simulink simulation software is used to compare and analyze the grid-connected active power response characteristics of energy storage VSG by using different control strategies under two types of disturbance, and the experimental platform of energy storage VSG grid-connected system is established. Simulative and experimental results jointly verify the effectiveness and superiority of the proposed AFDC-VSG strategy in optimizing the grid-connected active power response performance for energy storage VSG. |
