Modelling of Grid-Connected PV-Systems Using Real Meteorological Data

This paper focuses on developing a PV -grid modelling approach accounting for the vast majority of activities and factors related to processing of raw meteorological data - estimation of GTI and internal cell temperature, creating, tuning grid connected PV power system and its MPPT control and last but not least automatic analysis of the simulated results. For verification purposes, 4 case study Matlab models were developed and simulated for 64 full days with real meteorological data- two Simulink power models accounting for size differences small(<5kWp) and medium (5-30kWp) and 2 configurations for systems with solar tracking and without. Then a third script for system energy performance analysis was created and presented.
