Modeling approach for extracting the single-diode model parameters and predicting PV modules performance

Modeling and Simulation of Simplified Quadruple Diode Solar PV Module Under Influence of Environmental Conditions and Parasitic Resistance

“…The SDM, depicted in Figure 1, is a traditional PV model that includes one diode connected with a light-generated current source I ph in parallel, alongside a series resistance 𝑅 𝑠𝑒 and a parallel admittance 𝐺 𝑝𝑎 (where 𝐺 𝑝𝑎 =1/𝑅 𝑝𝑎 ) [18]. This model, called five parameters model, comprises 𝐼 𝑝ℎ , 𝐼 𝑟𝑠 , 𝑛, 𝑅 𝑠𝑒 , and 𝑅 𝑝𝑎 [19], [20], [21]. Although it offers advantages, its accuracy diminishes when irradiance levels decrease.…”

“…During the short circuit condition, the greatest value of the current extracted in a PV cell, which is produced by the short circuit condition, (𝑉 𝑜 ) is equal to zero and (I) is equal to (𝐼 𝑠𝑐_𝑆𝑇𝐶 ). Substituting these values into the Equation ( 9), the light-generated current is derived as follows: The iteration process enables the estimation of the values of 𝑅 𝑠𝑒 1T and 𝑅 𝑝𝑎 1T by utilizing equation (21).…”

An adaptable method for efficient modeling of photovoltaic generators’ performance based on the double-diode model

“…The one-diode model with five electrical parameters and the two-diode model with seven parameters are the most adopted by the authors [ 9 , [12] , [13] , [14] , [15] , [16] ]. To reduce the complexity and the nonlinearity degree of the current equation, the single-diode model is extensively employed in academic research [ [12] , [13] , [14] , [15] , [16] , [17] , [18] ]. However, since it ignores the impact of the recombination process within the depletion area, the single-diode model does not give the correct description of the physical effects inside real PV cells, and it is considered as a non-effective model [ 19 ].…”
