基于改进BP-SVM-ELM与粒子化SOM-LSF的微电网光伏发电组合预测方法
Combined Forecasting of Photovoltaic Power Generation in Microgrid Based on the Improved BP-SVM-ELM and SOM-LSF With Particlization
摘要
Abstract
ABSTRACT:Aimed at the difficulty of highly-accurate short-term forecasting of photovoltaic power generation in microgrid, a combined method with a new spatial view which only considers the direct relations among micro-sources was proposed. Back propagation neural network with the optimization of mind evolutionary computation, support vector machine with the optimization of particle swarm and extreme learning machine based on the single-hidden layer feed- forward neural network were used to forecast respectively. Variance- covariance combined method solved the problem of dynamic weight distribution. One day prediction and rolling prediction employ another method. This method used Kohonen's self- organizing feature map with particlization and least squares fitting to output results with equal weights. The simulation tests show that the proposed approach has high complementation, better flexibility and accuracy. It can provide a superior technical reference for the optimized operation of microgrid.关键词
