由于光伏发电具有间歇性、波动性的特点,因此准确预测并网型光伏发电系统的输出功率对电网调度,以及电网的安全稳定和经济高效运行具有重要意义.提出了一种基于相似日理论和LIBSVM软件中支持向量机回归(SVR)算法的光伏发电系统输出功率预测方法.通过实例进行仿真验算,并与同样采用相似日理论的反向传播(BP)神经网络算法、径向...
PV power generation has the characteristics of intermittent and volatility.Accurately predicting the output power of PV power generation systems plays an important role in grid dispatching,safe and stable operation.This paper presents a prediction method of output power of PV power generation system based on similar day theory and SVR algorithm of LIBSVM software.The simulation of the example and the comparison with the BP neural network algorithm,RBF neural network algorithm and Elman neural network algorithm prove that the prediction method is effective.
