Standardization of the adequacy of electric power systems and formation of the reserve of the generating capacity

The paper is devoted to the topical issue of determining the required total capacity reserve for a given level of adequacy when managing the development and operation of the Unified Electric Power System of the Russian Federation. The problem of reserving energy capacities is, first of all, the problem of ensuring the reliability of energy systems, electrical power supply systems. Whereas the reserves themselves are only one of the ways (though the main one) to ensure reliability, in particular, reliable and high-quality equipment, regular and high-quality repairs, highly professional services, material and financial supply and other measures. In terms of standardization the reliability of power consumption, it is advisable to standardize the adequacy, and not the reserves of generating capacities. This is due both to the generally accepted practice (including foreign ones) and to the fact that the adequacy standard determines both the required reserve of generating capacity and its placement in the system, taking into account the capacity of the ties. However, in this paper, the main emphasis is on the close interdependence between adequacy and total capacity reserve. Obviously, the higher the adequacy, the larger the reserve should be. Based on the requirement to apply one or another adequacy standard, authors offer to assess and calculate the adequacy indices including the probability of failure-free operation. Moreover, the calculated reserve should be considered complete and necessary, but not normative, to maintain the given level of adequacy. The paper analyzes and shows only three calculations on the example of the IPS of Siberia. Multivariate calculations have really shown that analyzing the indicators of adequacy allows you to get not only the required capacity reserve, but also see those territories where it is necessary to take appropriate measures to ensure reliability.
