基于 LM 算法的 BP 神经网络的电力负荷短期预测
Power System Short-Term Load Forecasting Based on Levenberg-Marquardt Algorithm BP Neural Network
摘要
Abstract
By utilizing the normalization for the input load values of BP neural network and adopting Levenberg-Mar-quardt algorithm,this paper established an improved BP neural network and investigated the power system short-term load forecasting.Levenberg-Marquardt algorithm improves the convergence speed and the load forecast accuracy.The simulation re-sults show that the improved BP neural network can offer higher forecast precision and has greater applicability.关键词
