摘要
随着新能源接入比例的不断提高,电池储能系统在现代电力系统中发挥着重要作用。模块化多电平电池储能系统(modular multilevel converter battery energy storage system,MMC-BESS)是规模化电池储能系统中较有前景的拓扑结构。以模块化多电平拓扑为基础,设计MMC-BESS试验平台。构建以DSP和FPGA为控制核心的主控制器,设计系统的通信方式与控制方式。针对实际系统,建立Simulink仿真模型,根据仿真结果设计适合实际系统的元件参数与控制器参数,完成实际系统的软硬件构建。在不同工况下对实际系统工作波形进行分析,证明了设计的有效性。
With increasing proportion of new energy access,the battery energy storage system plays an important role in modern power systems.The modular multilevel converter battery energy storage system(MMC-BESS)is a promising topology in large-scale battery energy storage systems.Based on the modular multi-level topology,a MMC-BESS experimental platform was designed.A main controller using DSP and FPGA as control core was constructed,and communication mode and control mode were designed for the system.According to the actual system,a Simulink simulation model was established.According to simulation results,component parameters and controller parameters suitable for the actual system were designed,and software and hardware construction of the actual system was completed.The validity of the proposed design scheme was verified through analysis of waveforms of the actual system under various working conditions.
