| Abstract: | Based on the similarity between mathematical models of microgrid voltage source inverter(VSI) and synchronous generator,a virtual synchronous generator model for three-phase VSI is established in this paper.The function of virtual induced electromotive force(EMF)is analyzed,and the control strategy that can be applied in virtual regulating system and virtual excitation system in microgrid inverter is proposed.The principle for system parameters design and the simulation model structure are presented.The mocrogrid inverters adopting the control strategy are capable of voltage/frequency regulation as well as power control.They can be used in both operation models of island and connection.Simulation analysis results verify the control strategy effectiveness. |
