A novel simulation model for PV panels based on datasheet parameter tuning

In this paper, a new PSIM simulation model for PV panels using online parameter tuning is presented. The proposed model utilizes only datasheet values measured under STC and excludes the necessity of the error-prone processes. Furthermore, all of the five parameters in single-diode model are successively tuned using Powell's optimization method in order to guarantee good accuracy and high speed. Comparisons with conventional model are performed using crystalline PV panel sample and the results shows that the proposed model provides more accurate and uniform performance according to EN50530 standard.
