The presence of a centralized power supply with the appropriate infrastructure and an extensive distribution network with significant technological losses not only causes increased risks, but also calls into question the quality and reliability of the energy supply of remote objects. The use of small power plants based on renewable energy sources can solve the problem of power supply of transport infrastructure objects (public transport stops, pedestrian crossings, traffic control elements, etc.). However, the expediency of using one or another energy source requires simulation modeling of the parameters of these power supply systems.
The purpose of this study is to develop a simulation model of the autonomous energy supply system of road infrastructure objects and to check its functioning in real conditions. The article describes the structural simulation model and presents the characteristics of its components. The order of functioning of the constituent elements and the peculiarities of their interaction are given. Experimental modeling of the dependences of the output power of the photovoltaic module on the voltage maintained at its output was carried out, and the obtained results were summarized.
The developed model makes it possible to implement the mode of maintaining maximum performance thanks to the introduction of feedback to control the value of the input voltage of the converter, which is compared with the calculated (set) value of the voltage, calculated from the data of the actual load current and short-circuit current of the photovoltaic module for different values of light flux. The result of the comparison, with the appropriate sign, is sent to the proportional-integral regulator, the output control effect of which is the regulation of the output voltage of the converter and, related to it, the charging current of the battery, which, therefore, leads to a change in the input current and ensures the maintenance of the set voltage at solar cell outputs. Under this condition, its output current is directly proportional to the amount of solar radiation. It is also established that the selection of the minimum required capacity of the photovoltaic panel must be carried out taking into account the most unfavorable scenario regarding weather conditions and the season of the year in order to ensure the maximum charge of the battery.
