Description: The model used for creating the reference voltage is shown
in Fig. 4. First, photovoltaic output current (Ipv) and output
voltage (Vpv) are passed through a first order low pass filter
with a magnitude of G = 1 and a time constant of T = 0.01
seconds in order to filter out the high frequency components
or harmonics from these signals as shown in Fig. 5 and Fig. 6.
The filtered current and voltage signals (Ipv_F and Vpv_F) are
then fed into the MPPT control block that uses the Incremental
Conductance Tracking Algorithm. An algorithm that is based
on the fact the slope of the PV array power curve shown in
Fig. 7 is zero at the Maximum Power Point (MPP), positive on
the left of the MPP, and negative on the right. The MPP can
thus be tracked by comparing the instantaneous conductance
(I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

Description: 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.)
