We estimated the time at which the rate of decline begins to accelerate (the changepoint), and the pre - and post-acceleration rates of decline, from the longitudinal data using a changepointmodel.
利用改变点模型从纵向数据中找出加速点、前加速期下降速率和后加速期下降速率。

It can overcome the nonlinear characteristics aroused by the change of model working point, and can also guarantee the decouple performance between the control loops.
它既可以克服模型工作点变化所带来的非线性问题，同时又可以保证控制回路间的有效解耦。

Through the single-dynamic load model dynamic reactive power compensation device can change the original system bifurcation point, increase the load limits and improve the system voltage stability.
