摘要(Abstract)：

在当前国家大力实施清洁能源战略的背景下,为提高电力系统概率潮流分析的准确性,设计了一种计及频率特性的高比例可再生能源电力系统概率潮流分析方法。首先建立交流潮流模型,将影响因素记作输入随机变量,得到系统潮流的随机变量线性组合形式;在此基础上,对输入随机变量进行相关性处理;最后,考虑系统频率偏差,对发电机出力进行迭代计算,实现概率潮流的实时计算。应用上述方法对IEEE 14节点算例进行概率潮流仿真计算,结果表明该方法在准确性方面具有明显优势,具有实际应用意义。
In the context of vigorous promotion of clean energy strategy in China, a probabilistic power flow analysis method of high-proportion renewable energy power system considering frequency characteristics is formulated to improve probabilistic power flow analysis accuracy of power system. Firstly, an AC power flow model is established, where the influencing factors are represented as random input variables, and the power flow of the system is obtained in the form of a linear combination of random variables. Then, the problem of correlated random variables is solved. Finally, in view of the system frequency deviation, iterative calculation on the output power of generators is carried out to realize real-time calculation of probabilistic power flow.The proposed method is employed in probabilistic power flow calculation on IEEE 14 bus, and the result shows that it is of superiority in precision and practicability.
