摘要(Abstract)：

多源多变换微电网整合中低压配电网中特性各异的分布式发电系统和负荷,多类型微电源、多类型负荷动态特性相互耦合、互相影响,传统以交流同步发电机供电电源为基础的系统稳定分析与控制方法无法满足多源多变换微电网大规模发展的要求。首先对近年来国内外多源多变换微电网大扰动暂态稳定性的研究进行评述,归纳总结可再生能源渗透率不断提升下微电网典型运行特性和存在的暂态稳定性问题。在微电网暂态稳定性分类的基础上,分别从微电网暂态稳定问题、暂态稳定分析方法和微电网暂态稳定性提高措施三方面对微电网暂态稳定性的研究动态进行分析、评价和探讨;最后,预测和探讨了微电网大扰动暂态稳定性研究的发展趋势。
