| 摘 要： | 风力发电出力具有间歇性、波动性和随机性的特点,风功率直接并网可能给电网的电压、频率稳定带来消极影响,这就需要在风电场中安装储能系统来平抑风力发电输出功率波动。介绍了电池储能功率转换系统的发展现状,给出了一种链式电池储能功率转换系统方案和功率控制方法,推导了通过零序电压注入和在各H桥单元交流输出电压附加相应的分量来实现相间电池簇和相内电池组荷电状态均衡的原理,在MATLAB/SIMULINK环境下进行仿真验证。

| Abstract: | Because of the time variable nature of wind, the wind generation is fluctuating. Directly connecting the intermittent active power to grid will deteriorate power quality and enhance the requirement to the dispatch. The battery energy storage smooth out the wind farm output active power fluctuation. In this paper, the different topologies for battery energy storage system are investigated. A cascaded H-Bridge power conversion system was implemented, and the control strategy for power and battery SOC (state of charge) balancing was designed. The MATLAB/SIMULIK simulation results which verify the validity of the control scheme was presented in this paper. |

| Keywords: | battery energy storage cascaded H-Bridge state of charge zero sequence voltage |
