Research on grid-connected technology of inverter based on quasi synchronous principle

In order to realize the inverter connected with grid friendly,in allusion to synchronverter based on synchronous generator model,this paper presents a grid-connected method based on quasi synchronous grid-connected idea for inverter.In view of synchronverter having some features which are similar to synchronous generator,a quasi synchronous grid-connected technology of synchronous generator will be combined with grid-connected technology of synchronous inverter,and a friendly and effective grid-connected method for inverter is given.Simulation with Matlab/Simulink is given to verify the feasibility of this method,and the results are analyzed.Simulation results show that the grid-connected method of inverter based on quasi synchronous grid-connected idea is feasible and effective,and this method can make the synchronverter connect with grid fast and friendly.
