PV shading fault detection and classification based on I-V curve using principal component analysis: Application to isolated PV system
Solar Energy(2019)
摘要
•Shaded PV cells degrade the performance of PV systems.•I-V curves contain useful information for health monitoring.•Data driven method for fault diagnosis can deal with non-controlled solar irradiance.•Principal component analysis has proven its efficacy under real working conditions.
