优秀论文及配套源码 SVM Short-term-Load-Forecasting
优秀论文及配套源码。首先阐述了负荷预测的应用研究现状，概括了负荷预测的特点及其影响因素，归纳了短期负荷预测的常用方法，并分析了各种方法的优劣；接着介绍了作为支持向量机（SVM）理论基础的统计学习理论和SVM的原理，推导了SVM回归模型；本文采用最小二乘支持向量机（LSSVM）模型，根据浙江台州某地区的历史负荷数据和气象数据，分析影响预测的各种因素，总结了负荷变化的规律性，对历史负荷数据中的“异常数据”进行修正，对负荷预测中要考虑的相关因素进行了归一化处理。LSSVM中的两个参数对模型有很大影响，而目前依然是基于经验的办法解决。对此，本文采用粒子群优化算法对模型参数进行寻优，以测试集误差作为判决依据，实现模型参数的优化选择，使得预测精度有所提高。实际算例表明，本文的预测方法收敛性好、有较高的预测精度和较快的训练速度。(first expounds the recent application research of load forecasting, summarized the characteristics of load forecasting and influencing factors, summed up common methods of short-term load forecasting, and analyzed the advantages and disadvantages of each method then introduced statistical learning theory and the principle of SVM as the basis of support vector machine (SVM ) theory, SVM regression model is derived this paper adopted least squares support vector machine (LSSVM) model, according to the historical load data and meteorological data of a certain area of Zhejiang Taizhou, Analysised the various factors affecting the forecast, summed up the regularity of load change , amended "outliers" in the historical load data,the load forecasting factors to be considered were normalized. The two parameters of LSSVM have a significant impact on the model, but it is still soluted based on the experience currently. So, this paper adopted particle swarm optimization algorithm to optimized )

在这篇文章中，我们给出了非线性脉冲和孤子耦合的理论，它包含了2阶3阶色散，模间色散，损耗增益，色散不匹配，高阶非线性等等。文章主要说明了几个非线性耦合的基本问题： 非线性脉冲耦合行为主要依赖于参量Lcd （色散长度乘耦合系数），而不是输入脉冲形状，因而，孤子，高斯脉冲以及类高斯脉冲表现出同样的开关特性。根据Lcd, 耦合器可分为三个工作区，每个区有自己独特的耦合行为。一个脉冲是否表现为连续波的耦合行为还是超快脉冲的耦合行为，决定于Lcd 而不是脉宽。 我们显示0.8皮秒的脉冲也遵从连续波的方程和耦合行为， 可以当连续波一样来分析。(study input peak power vursus output total power for different Lcd, P~P CURVES )
