Maximum Power Point Tracking approach based on Temperature for PV Surfaces using PSPICE program

     This research study the effect of Photovoltaic surface temperature on Photovoltaic panel output characteristics. First,circuit simulator PSPICE was used to compose Photovoltaic panel model at 75 W, 4.8 A and 21 V. Then, study the behavior of it under varying conditions (solar insolation, environmental temperature and PV panel surface temperature). ABM feature of PSPICE was used to include the above rameters in PV PSPICE model and produced temperature dependent voltage. The voltage converted to current with galvanic insolation by element Gploy with gain 0.8. The model defined as hierarichal block in PSPICE library and could be called as individual source for any applications. After studying the effect of PV surface temperature on its (IV) curves specially the position of the maximum power point,this temperature was used to keep tracking of the optimal voltage for the PV panel at the MPP. Therefore DC -DC boost converter was used to achieve this purpose. Boost converter was raise a PV panel voltage from 17 V to 34 V for all variation of surface temperature from 300 K to 350 K at frequency 10 KHz and ∆V = 5 V.o
