经济学家开拓了一种试图分析变量之间的格兰杰因果关系的办法，即格兰杰因果关系检验。该检验方法为2003年诺贝尔经济学奖得主克莱夫·格兰杰（Clive W. J. Granger）所开创，用于分析经济变量之间的格兰杰因果关系。他给格兰杰因果关系的定义为“依赖于使用过去某些时点上所有信息的最佳最小二乘预测的方差。”(granger causality test)

连续潮流：又称为延拓潮流，是电力系统电压稳定性分析的有力工具，它通过在常规潮流基础上引入一个负荷增长系数来克服雅可比矩阵奇异，从而克服接近稳定极限运行状态时的收敛问题，解决了常规潮流在崩溃点外无解和在崩溃点附近不能可靠收敛的问题。连续潮流法是从初始稳定工作点开始，随着负荷缓慢变化，沿相应的PV曲线对下一工作点进行预估、校正，直至勾勒出完整的PV曲线。(Continuous flow: also known as the continuation of the trend, is a powerful tool for voltage stability analysis of power system, by introducing a load growth coefficient to overcome Jacobi singular in the conventional power flow basis, so as to overcome the convergence problem near the stability limit of the running state, to solve the conventional power flow solution and in near collapse point reliable convergence problem in the collapse point. The continuation power flow method starts with the initial stable working point. With the slow load change, it predicts and corrections the next working point along the corresponding PV curve until the complete PV curve is outlined.)

看到的比较详细的GA遗传算法源代码，功能应该比较全，大家可以下载试试(See the more detailed GA genetic algorithm source code, the function should be more complete, you can download and try.)

说明：  对控制系统各组成部分的控制规律进行分析和数学抽象，建立局部数学模型，得到一些典型的控制环节。复杂系统是由典型控制环节组成的。(Control system of the various components of the control law analysis and mathematical abstraction, the establishment of local mathematical model, some aspects of a typical control. Complex system is composed of a typical control links.)
