未来的电网必须能够管理来自不同电网以及可再生能源（RES）和其他分布式发电（DG）系统的能量。先进的电力电子转换器可以提供控制功率流的手段，并确保未来网络的正确和安全运行。本文介绍了一种背靠背三相AC-DC-AC多电平变换器的分析，设计和实验验证，用于未来电网的通用和灵活的电源管理（ACTLEX-PM）及其先进的控制技术。所提出的系统已成功地测试了双向功率流操作与不同的电网运行条件，如电压不平衡，频率变化，谐波失真，短路故障。
The future electricity network has to be able to manage energy coming from different grids as well as from renewable energy sources (RES) and other distributed generation (DG) systems. Advanced power electronic converters can provide the means to control power flow and ensure proper and secure operation of future networks. This paper presents analysis, design, and experimental validation of a back-to-back three-phase ac-dc-ac multilevel converter employed for universal and flexible power management (UNIFLEX-PM) of future electrical grids and its advanced control technique. The proposed system has been successfully tested for bidirectional power flow operation with different grid operating conditions such as voltage unbalance, frequency variation, harmonic distortion, and faults due to short circuits.
