Optimization of Power Supply System of Agricultural Enterprise with Solar Distributed Generation

Today, the activities of most enterprises are partially, and in some organizations, fully automated, that is why power outages lead to the interruption of all technological processes, financial damage to enterprises and various problems in the communal sector during power outages. One of the options for ensuring uninterrupted energy supply, improving the quality and reliability of power supply to consumers in rural and remote areas in cases of accidents in distribution networks can be considered the use of renewable energy sources. The purpose of the research is to optimize the configuration of the power supply system of agricultural enterprise by using solar power plants. The object of the research is the power supply system of the production facility of the agro-industrial complex. There was conducted calculation of the number of photovoltaic modules that can be placed on the roofs of agricultural enterprise to achieve maximum electrical energy generation during the day. On the basis of experimentally obtained data of currents and voltages, the generated power of photovoltaic modules was determined. The ratio of the maximum generated power of the south-oriented module located at tilt angle of 15° to the maximum generated power of the south-oriented module located at the optimal tilt angle of 39° was also determined. The average value of the ratio of the maximum generated power of the south-oriented PV module located at tilt angle of 15° to the maximum generated power of the south-oriented panel located at optimal tilt angle of 39° was calculated. The total daily production of electrical energy by all solar power plants is 885.22 kWh per day for a given date (Nov. 1). The ratio of daily electricity generated by solar power plant to that consumed by production facility in the specially selected city of Russia (Zernograd) is 71.8%.
