Abstract
The results of modeling and investigation of solar photovoltaic power plant modes with maximum power tracking controller are represented. The most widespread methods for maximum power point tracking of solar panels are considered. The DC voltage method, no-load method, short circuit method, method of random disturbances and conductance increment method are reviewed. Complex photovoltaic plant model, including solar panel, power converter with controller, is created. The results of system’s operating modes simulation when changing the insolation and the temperature of the solar cell are represented. The review of the various methods to search for the maximum power of the solar cell conducted and the analysis of their performance under different climatic conditions can be useful for a wide circle of professionals in the field of photovoltaics. All the proposed models of photovoltaic systems components are implemented in MATLAB/Simulink, which allow their use after a simple revision for the investigation of any systems with other types of converters and maximum power tracking controllers.
