说明：  处理主动源和被动源面波数据，可拾取频散曲线(Processing active source and passive source surface wave data, picking up dispersion curve)

说明：  三相光伏并网逆变器MATLAB/simulink仿真模型(MATLAB/simulink simulation model of three-phase photovoltaic grid-connected inverter)

说明：  是一个完整的1.5MW双馈风机简化模型，输入是风速，输出是功率，还没有做到并网模块(It is a complete simplified model of 1.5MW doubly fed fan. The input is wind speed and the output is power. The grid connection module has not been achieved)

基于随机邻域搜索的含风电配电网优化规划 本程序提出了含风电配电网中基于半不变量的随机潮流算法，该算法考虑了风电的出力随机性，运用了概率统计方法处理系统运行中的随机变化因素，给出系统运行电压、支路潮流等概率分布情况，可以更深刻地揭示系统运行状况，为系统安全运行决策提供更完整的信息。 随机变量的卷积运算是随机潮流计算量较大的部分，利用半不变量的方法进行随机变量间的卷积运算，并用Gram-Charlier级数展开式计算随机变量的分布[4-6]将使整个随机潮流计算效率很高，其精度也足以满足规划和运行分析的要求。(This code package mainly analyzes the characteristic of smart grid and the influence RES bring to distribution networks. In this paper, evaluation was made for the necessary improvements on intelligentizing transformation from different aspects, such as load forecast, power stationing planning and network planning, which will truly provide theoretical guidance for the planning work of intelligent distribution networks.)

四机两区算例(4机2区算例),与昆德(Kunder)书中参数一致，包含详细的发电机模型，算例在PSCAD4.2中可以运行，是学习PSCAD难得的资料。(The four-machine two-zone example (4-plane 2-zone example) is consistent with the parameters in Kunder s book, including detailed generator model. The example can be run in PSCAD4.2, which is a rare learning material for PSCAD.)

说明：  对于已知的电路结构，求解其网络分析的状态变量法(For the known circuit structure, the state variable method is used to solve the network analysis)

说明：  有源电力滤波器 绝对可以运行，参数自己可调，PR控制(Active power filter based on PR control)
