This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells. The DVR restores constant load voltage and voltage wave form by injecting an appropriate voltage. Present novel structure improves power quality by compensating voltage sag and voltage swells. The transient response of any natural system is the way in which the response of the system behaves as a function of time. Electromagnetic transient studies have always played an essential behavior of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. This project addresses the transient studies of electrical networks with embedded, power electronics-based, FACTS and Custom Power (CP) controllers.

用雅克比迭代法解椭圆型方程，这是椭圆型方程的差分解法。见于孙志忠编的《偏微分方程数值解法》的p41例题( Solutions of Elliptic Equations with Jacques iterative method, which is the solution of elliptic differential equations. Seen SUN Zhi-zhong series "Numerical Solution of Partial Differential Equations" examples of p41)

说明：  ARIMA 模型是在平稳的时间序列基础上建立起来的，因此时间序列的平稳性是建模的重要前提。检验时间序列模型平稳的方法一般采用 ADF 单位根检验模型去检验。当然如果时间序列不稳定，也可以通过一些操作去使得时间序列稳定（比如取对数，差分），然后进行 ARIMA 模型预测，得到稳定的时间序列的预测结果，然后对预测结果进行之前使序列稳定的操作的逆操作（取指数，差分的逆操作），就可以得到原始数据的预测结果。(time series prediction ARIMA)
