The use of renewable energy sources and in particular solar energy has received considerable attention in recent decades. Photovoltaic (PV) energy projects are being implemented in very large numbers in many countries. Many research projects are carried out to analyze and verify the performance of PV modules. Implementing a pilot plant for a photovoltaic power system with a DC / DC converter to test system performance is not always possible due to practical limitations. The software simulation model helps to analyze the performance of PV modules, and more useful would be a general circuit model that can be used to test any commercial PV module. This paper presents a simulation of a mathematical model of a photovoltaic module that boosts a DC / AC converter and also simulates the operating modes of a solar generating system at various load characteristics. The model presented in this article can be used as a generalized PV module to analyze the performance of any commercially available PV module. In the presented work, the parameters that affect the performance of the generating system were investigated. The results were obtained for the operation of DC/AC photoelectric converters. The presented characteristics strongly depend on such parameters as solar insolation, the temperature of the working surface of the photovoltaic module, the charge-discharge time of storage batteries, etc. When one of the values of these parameters changes, the operating modes of the solar power generating battery change. Changing the operating modes can lead to malfunctions of the entire operation of the system, therefore, it is necessary to control all the energy characteristics of the installation. The actions proposed in this work aimed at studying the operation of the photovoltaic system and the energy storage system, as well as the use of the necessary auxiliary devices for monitoring and controlling the parameters of the installation, are capable of achieving an increase in the efficiency of the generation of the system. The studies carried out in the course of the presented work make it possible to increase the level of knowledge on the control and management of the parameters of photovoltaic generating plants and expand the possibilities of their uninterrupted operation and increase energy production.
