Investigation of the Impact of the Alternative Energy Generation Variable on the Operation of Interconnected Energy System

Abstract

The aim of the work was to analyze the efficiency of solar and wind power plants when they work as part of an integrated power grid using the example of the IPS of the South, to determine the share of electricity that can be generated at RES facilities, taking into account their intermittent operation, and to assess the possibility of balancing the network with a decrease in RES generation at night and in calm weather at the expense of electricity from wind farms in other regions of the IPS of the South. An analysis of the possible generation of electricity by renewable energy facilities showed that with an installed capacity of 13% per year, they will be able to meet 3.5% of the needs of the regions included in the UES of the South. During the day, the maximum consumption was recorded in the region of 11-12 hours and 19-21 hours. Solar generation has a maximum at noon, so it can compensate for the daily peak in consumption. In the evening hours, wind generation and solar generation are minimal. Therefore, they cannot be used to compensate for increased consumption, and traditional generation is necessary. As a result, it is not possible to reduce the installed capacity of traditional RES generation. To compensate for the decrease in WPP generation in summer, the installed capacity of WPP and SPP should be equal, and at present, in the IPS of the South, the capacity of WPP exceeds the capacity of SPP twice
