摘    要:针对传统断面极限离线仿真算法计算量大、计算时间长,难以满足多运行方式精细化管理等问题,提出了一种数据驱动的基于最小冗余最大相关和AdaBoost的新型电力系统断面极限估算方法。首先对电力系统运行特征与断面极限进行相关性分析,采用最小冗余最大相关算法提取系统关键特征;然后利用AdaBoost算法进行断面极限的回归分析。实际电网算例估算结果表明了所提方法的有效性。

关 键 词:断面极限  数据驱动  mRMR  AdaBoost

Abstract:The traditional offline simulation algorithm of section limit is computationally intensive and takes a long time to calculate,is difficult to meet the refined management of multiple operation modes. A new data-driven power system section limit estimation method is proposed based on minimum redundancy maximum correlation and AdaBoost. Firstly, the correlation between power system operation characteristics and section limit is analyzed,then the minimum redundancy maximum correlation algorithm is used to extract the system key features. Then AdaBoost algorithm is used for the regression analysis of section limits. The estimation results of real power grid example show the effectiveness of the proposed method.
Keywords:section limit  data-driven  mRMR  AdaBoost
