I want to compute 'I pv' , 'I o' , 'R s' , 'R p' and 'a' using Non linear least square method. Although the problem appears simple one can use fsolve or nonlsqlin etc with system of non linear equations in matlab but i am unable to compute the correct values. This is the reference research paper i used
B. K. Nayak, A. Mohapatra, and K. B. Mohanty, “Parameters estimation
of photovoltaic module using nonlinear least square algorithm: A
comparative study,” in Proc. Annu. IEEE India Conf., 2013, pp. 1–6.
Kindly help me with the matlab code for NLS method.
Thanks
You can implement a simple I-V and P-V curve tracer fusing MATLAB. In your code you have to specify all the factors, But you always can play with these values to check the suitable values for your PV.
So, you can run the prgoramme and simulated the PV data. Compare and change all values again and again to have the best output performance for the PV system you intend to implement.
Sir, i want to compute single diode model parameters using non linear least square method. I have to compare non linear square method with other parameter extraction methods available.
Thanks
Dear Affan,
My advice is to start the iterations of the least square error,with an estimate of the parameters which is accurate as possible. So to estimate the intended parameters please follow the method which i developed in the link;https://www.researchgate.net/post/Solar_cell_parameter_extraction_from_a_single_I-V_curve
Wish you success
