Study on Complex Oscillation Problems Caused by Grid Connection Systems of New Energy Sources and Countermeasures
Affected by the interaction of power electronic converters and other factors,there exist complex oscillation problems in grid connection system of new energy sources.Combined with the oscillation mechanism,the main manifesta-tions of the oscillation problem caused by grid connection systems of new energy,and the analysis results are combined to maintain the stability of the new energy grid-connected system,which is to have a stable manifold as the core,and a rea-sonable damping controller is constructed to realize the suppression of the oscillation.In the test results,the corresponding active power oscillation amplitude is the lowest,and the number of oscillations is the smallest,which has obvious advanta-ges compared with the control group.
