摘要
针对风机、光伏等分布式微电源出力随机、间歇的特征,为提升绿色能源供电质量,提出了一种混合储能多模式下垂充放电控制策略。根据预期设定的直流母线电压波动幅值和各储能的荷电状态约束条件,系统自动选择储能设备的充放电工作模式,能够快速调整混合储能系统的功率输出及直流母线电压波动问题,满足了系统功率平衡需求。最后,采用大型综合仿真软件PSCAD/EMTDC进行了仿真测试。结果表明:该方法合理、可行,具有工程应用价值。
In order to improve the quality of green energy power supply, in view of the random and intermittence characteristics of distributed micro-sources such as fan and photovohaic, this paper put forward a droop charging and discharge control strategy for the hybrid energy storage muhi-mode. According to the pre-setting voltage fluctuation of DC bus and every constrain｜ condition for storage state of charge ,this system can choose charging and discharge work mode for energy storage equipment. And the power output of hybrid energy storage and w^hage fluctuation of DC bus could be adjusted rapidly. Lastly,it was shown by the PSCAD/EMTDC simulation system, that this method is reasonable and feasible and has engineering application value.
