摘要
电池储能是目前最有前景的储能技术之一,模块化多电平换流器(MMC)广泛应用于柔性直流输电领域。将电池储能与MMC相结合,构成储能型MMC。由于其具有电池系统、交流电网与直流电网间功率交换的功能,导致与传统MMC的控制方法不同。分析了储能型MMC的结构与工作原理,研究了多种运行工况下换流器功率解耦控制方法,搭建了仿真与实验样机,验证了所提控制方法的正确性和有效性。
Battery energy storage has been one of the most promising energy storage technologies.Modular multilevel converter(MMC) has been widely used in HVDC transmission.Battery energy storage is connected with each submodule of MMC to form a MMC with energy storage.Because it have the function of power exchange among battery system,AC grid and DC grid,its control method is different from traditional MMC.The structure and principle of MMC with energy storage are analyzed.The power decoupling control method for multi-operating modes is proposed.Simulation and experimental prototype are built to verify the correctness and effectiveness of the proposed control method.
