With the large-scale integration of renewable energy into off-grid DC systems, stability issues caused by their fluctuations have become increasingly prominent. The dual active bridge (DAB) converter, as a DC-DC converter suitable for high power and voltage level plays crucial role in maintaining regulating grid through its control methods. However, existing methods DAB are inadequate: linear fails to meet dynamic response requirements, while nonlinear relies on detailed model structures...
Abstract Aiming at the problem that fault suppression effect is not obvious due to unclear type of ferroresonance, an improved Elman-Adaboost method for classification and identification ferroresonance was proposed. Firstly, characteristic values different types overvoltage were extracted, then a classifier added traditional model automatically find optimal hidden layer, corresponding weighted parameters adjusted when training set recognized correctly. Finally, by constructing two-stage test...
