Modeling an autonomous photovoltaic system in the MATLAB Simulink software environment

The possibility of constructing mathematical models of any photovoltaic module with known indicators of the module surface temperature and solar radiation is shown. As a result of modeling, the dependences of the current-voltage characteristics of the module on temperature and solar radiation were obtained. A mathematical simulation model of an autonomous photovoltaic system has been developed, which includes photovoltaic modules, an inverter, an LCL filter, a single-phase transformer and consumer of electrical energy. Simulation modeling was performed in MATLAB Simulink environment. is considered the problem of high-quality and uninterrupted power supply of decentralized zones. Today, this problem is one of the most important and priority tasks of the domestic energy sector. The authors of this article consider the issue of providing electricity to such consumers using a mobile scalable energy complex based on renewable energy sources. The main content of the article is aimed at creating and analyzing a model of a mobile energy complex in the MatLab software environment. The model of the energy complex will consist of several elements: photovoltaic power plants and batteries, which will be created using block diagrams. To analyze the model, we entered arbitrary initial data: meteorological parameters; the number and capacity of batteries; the area of solar modules; the load graph; the power of photovoltaic power plants. The theoretical test site of the model was adopted in Tashkent.
