An iterative approach for modeling photovoltaic modules without implicit equations

Single-diode Models of PV Modules: A Comparison of Conventional Approaches and Propose a Novel Model

“…Although these models impose no restrictions on the problem formulation [11], metaheuristic algorithms might take long computational time and convergence difficulty. Meanwhile, in [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][29][30][31][32][33][34][35], analytics methods utilize a set of mathematical equations and assumptions from the datasheet provided by manufacturers. The trade-off between model accuracy and computational time makes the analytics methods much popular in engineering applications than metaheuristic methods.…”

“…A PV cell is described by an equivalent circuit consisting of a current source, at least one diode, and one resistor [15] based on the intrinsic characteristics. The single-diode model (SDM) [13,16,17] and the double-diode model [11,18,19] have gained the most researchers' attentions, specifically the SDM. Although the double-diode model has a certain advantage, that is representing the recombination loss in the depletion region [20], the double-diode model requires solving an implicit nonlinear seven-parameters [11].…”

“…Different methods have been proposed to extract five parameters of the SDM. In [12][13][14][15][16][17][18][19][20][21], a set of implicit equations accompanied by assumptions and simplifications were used to formulate the equations obtaining the model parameters.…”

“…An iterative and analytical method are conducted by [13,17,22], which proposed a method to estimate parameters through a trial-and-error approach.…”

A Novel Method Based on Bisection Search Algorithm for Extracting the Reference Parameters of Pv Modules

“…In order to design an efficient PV system, it is important to predict PV device behavior accurately at all operating conditions. The most common technique to simulate the characteristic of PV devices is to use an equivalent circuit model [2]- [9]. The main challenge when using methods based on equivalent circuit models is how to extract the parameters that ensure accuracy in various operating conditions.…”
