PARAMETER EXTRACTION OF SINGLE-DIODE PV-MODULE MODEL USING ELECTROMAGNETISM-LIKE ALGORITHM
The performance of photovoltaic (PV) module mainly depends on the parameters of electrical equivalent circuit of module. The parameters are unknown and sensitive to meteorological condition of PV location. Thus, an accurate estimation method should be used to extract the parameters. In this paper, an evolutionary algorithm proposed to optimize the parameters under various operation conditions. The root mean square error between the computed current based estimated parameters and experimental PV output current is proposed as a fitness function to obtain the optimal solution. The results are verified by seven different experimental I-V sets under various meteorological conditions. Furthermore, the results are verified by another work, which based on analytical method that proposed in literature. The results refer to high consistency with realistic data. In addition to that, the proposed method offers an average root mean square error and average absolute error under seven operation conditions were 0.07248 and 0.05316, respectively.
