Mathematical modeling of a hybrid wind-solar station for power supply of own needs

The article presents mathematical modeling of a hybrid power plant (GEU) operating on renewable energy sources. The GEU includes a wind module, a solar module, and an electric power storage system. It is supposed to use the GEU for power supply of the botanical garden's own needs, the principle of operation of the station is described. The analysis of monthly data of average insolation and average values of wind speed in the Orenburg region is carried out. The real schedule of loads of the botanical garden is used for calculations. The analysis is based on data on solar insolation and wind speed over the past 20 years. It is revealed that the greatest generation of solar electricity during the year occurs in the period from June to July, and the greatest generation of wind electricity during the year occurs in the period from January to March. The total generation makes it possible to provide the botanical garden's own needs with electricity in any month except October and November. The excess electricity generated in the summer can be used for the production of hydrogen, which is used as fuel for a hydrogen fuel cell or its storage in storage devices.
