In this paper, a control structure is used that allows the connection of distributed generation sources as well as energy storage to the DC link of smart transformer (ST). This feature makes it possible to continue feeding the loads connected to the ST in emergency situations such as grid faults. The control method used is able to compensate for the imbalance as well as absorb the destructive harmonics of the power grid. This control method and the proposed structure make it possible to compensate for the unbalanced, as well as eliminate the harmonics caused by the side feeders and prevent it from being injected into the network. The performance of the control structure and method used in this paper has been demonstrated by simulating a sample system using Matlab / Simulink software.

在本文中，使用的控制结构允许将分布式电源和储能连接到智能变压器 (ST) 的直流链路。此功能可以在电网故障等紧急情况下继续为连接到 ST 的负载供电。所使用的控制方法能够补偿不平衡并吸收电网的破坏性谐波。这种控制方法和建议的结构可以补偿不平衡，并消除由侧馈线引起的谐波并防止其注入网络。本文所使用的控制结构和方法的性能已经通过使用 Matlab/Simulink 软件对示例系统进行仿真得到了证明。
