| Abstract: | Aiming at the technology of virtual synchronous generator(VSG)in microgrid,the VSG control strategy suitable for island microgrid was put forward firstly,and its detailed analysis and introduction was made.Secondly,considering the dynamic characteristics of parallel system when switching on and off loads for different capacities of VSG in parallel,a parameter design method based on inertial time constant matching and impedance matching was proposed to make the active and reactive power of VSG parallel system have good dynamic characteristics in the process of switching load.Finally,Matlab/Simulink simulation results and low power experimental results verify the correctness and effectiveness of the control strategy and parameter design method proposed in this paper. |
