Are IEC 60891 I-V curve correction methods suitable for I-V curves measured from PV modules under faulty conditions?

Abstract : Photovoltaic (PV) I-V characteristic (I-V curve) contains rich information about the status of the PV module or array; therefore, the I-V curve-based PV diagnosis has always been a popular issue [1]. Among this, the correction of I-V curves measured under various environmental conditions to an identical condition is usually a crucial step. However, there is no specific method dedicated to the correction of faulty I-V curves. Therefore, the correction procedures proposed in IEC 60891 standard [2] are commonly adopted, which, however, have only been validated for the correction of curves for healthy PV modules. Thus, this paper aims to evaluate the performance of the IEC 60891 single curve-based methods, i.e., procedure 1 (P1) and 2 (P2), for the correction of faulty I-V curves.
