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):

这个是用fortran编写的地球物理反演程序，十分经典。一般很难下载到，因为我是学生，所以才有机会跟老师处获得代码，请大家本着学习的目的使用代码，不要用于商业用途和随意转播(This is prepared by fortran geophysical inversion procedure is very classic. Generally very difficult to download because I am a student, so teachers have a chance to obtain the code, please use the spirit of learning of the code, not used for commercial purposes and not to broadcast)
