Application of a systematic approach to improving the efficiency of power supply modes of the Republic of Crimea

Abstract

The structure of the region’s energy supply is considered, the characteristics of all the major groups of electricity producers in the region, including thermal power plants, mobile gas turbine power plants, renewable energy sources, backup power sources, are presented. As tariffs in the transport problem under consideration, depending on the purpose of the calculations, it is proposed to use the averaged actual values in a given period of time according to the energy supplying organizations (the purpose of the calculations is to reduce the cost of production and transportation of electricity), and also conditional qualitative assessments - “fines” (The goal is to improve the environmental and reliability of the system as a whole). The influence of the generated power of solar power plants on the operation modes of the power system of the Crimea is investigated. A methodology has been developed to optimize the production of solar power plants that affect the reliability and quality of power supply. The calculation of different scenarios of energy supply of the Crimea carried out, including at peak and average modes of power consumption, with different variants of solar activity, the time of year, taking into account and without taking into account the energy sources under construction, repair works of sources in the off-season. Based on the results of the calculations, conclusions are made about the reliability of the power system in the region under different scenarios of power supply, as well as the need to use the power bridge for the flow of electricity from the mainland in both directions.
