Model Predictive Current Control of Active Distribution Transformer With Consideration of Its Stability Analysis Based on AC-AC Matrix Converter

摘要

In order to reduce the complexity of the algorithm, this paper proposes to apply model predictive current control (MPCC) to matrix converter-based active distribution transformer (MC-ADT). The proposed control strategy is to control the power factor of the input and the voltage on the output side. In order to ensure stability of the system, analysis of the output voltage is carried on under the Back-EMF R-L load. And the Rolls criterion is used to analyze the stability of the system. Simulation and experimental results verify the feasibility of the proposed control strategy and the stability of the system.
