MODELING THE OPERATION OF A PHOTOVOLTAIC MODULE IN SHADING CONDITIONS

Galina Cherneva, Hristina Spiridonova,Martina Tomcheva

The optimal operation of photovoltaic panels strongly depends on the environmental conditions - intensity of sunlight and temperature. Climatic conditions have a strong influence on the electrical characteristics of the panel - current, voltage, output power, volt-ampere characteristic. When designing photovoltaic plants, it is necessary to evaluate in advance their change under real conditions different from the standard test conditions for the panel. This s adequate modeling of the photovoltaic module with the possibility of studying under reduced solar radiation.

The laboratory bench for the study of an autonomous photovoltaic system, developed in the Department of ”Electrical Engineering and Physics” at VTU ”T. Kableshkov”.

In the present work, a simulation model of the photovoltaic panel in the Matlab/Simulink environment, used for the bench, is reworked to simulate its operation in shading conditions. The volt-ampere and power characteristics of the panel at reduced intensity of sunlight were obtained, which can be compared with the actual measurements.
