Solid State Transformer (SST) has many attractive characteristics, including power quality improvement and reactive power compensation. The paper investigates the topology and control schemes of SST, and discusses its flexibility and reliability for both grid and customers. A model of SST applied for distribution network is constructed, and simulation shows the SST with appropriate control scheme can provide excellent power supply during both steady-state and dynamic-state with varying load.

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.
