| 摘 要： | 针对电压稳定裕度问题,提出一种基于BP网络的新算法——代价函数BP网络法,该方法采用动态的BP网络对非线性电力系统的潮流进行在线学习、训练,最后计算得出电压稳定裕度.改进过程是将Frobenius范数的平方作为标准误差值,且利用回归分析将相关系数按照大小排列,删除相关程度小的数据,这样有效地减少了BP网络输入维数,提高... |

| Abstract: | BP network algebra algorithm,a new algorithm,based on BP algorithm,is presented for voltage stability margin.This method adopts moving BP network to learn online and train for nonlinear power system trends,and calculates voltage stability margin.Algebra algorithm makes the square of Frobenius norm as the standard error value,and arranges for correlation coefficient,to delete the little correlation’s data.It reduces the BP network input dimension and the calculating speed is improved.To IEEE39 node system for example,it calculates voltage stability margins,and shows that the accuracy of this algorithm. |
| Keywords: | BP network cost function multiple regression analysis voltage stability margin |
