Graphical Abstract:


Background: This paper presents a decoupled control technique for balancing the power and voltage through grid side converter using a solid state transformer.

Methods: Decoupling control is essentially a voltage oriented control technique with the objective of eliminating cross-coupling elements. Use of this decouple technique, allows bi-directional power flow control for both active and reactive power, thereby maintaining steady state DC interference voltage.

Results: The performance of this scheme is analyzed & the results are obtained from the Matlab/Simulink model.

Conclusion: From the above analysis, it can be concluded that the decoupled control strategy can easily eliminate the cross- coupled element of a solid state transformer for the grid side converter.

Keywords: Grid side converter (GSC), solid state transformer (SST), voltage oriented control (VOC), dual active bridge (DAB), direct power control (DPC), decoupled controller (DC).
