摘要: 提出一种基于多元回归的多断面有功潮流的控制算法,首先提取与断面潮流关联性较强的系统特征量,使用皮尔逊相关系数计算提取特征量与各个断面潮流的相关系数;接着根据相关系数对提取特征量进行筛选并进行多元回归分析;继而提出迭代多断面潮流最优控制求解模型,使用该模型对给定的断面潮流调整量计算出发电机出力调整量。最后采用IEEE 39节点系统对提出的算法进行仿真验证,结果表明该算法不仅能够实现对多断面有功潮流的精确控制,且计算速度快。

Abstract: A control algorithm based on multiple regression for multi-section active power flow is proposed in the paper.Firstly, the feature quantities with strong correlation with cross-section power flow are extracted.The Pearson correlation coefficient is used to calculate the correlation coefficient between the extracted feature quantity and the power flow of each section.According to the correlation coefficient, the extracted feature quantity is screened and multiple regression analysis is performed.Then, a multi-section power flow optimal control solution model is proposed.The model is used to calculate the adjustment amount of generator output for a given cross-sectional power flow adjustment.Finally, the proposed algorithm is verified using IEEE39 bus system, and the results show that the algorithm can not only accurately control the active power flow of multiple sections, but also calculate quickly.
