Abstract

One of the most important goals of the energy industry is to ensure a shortage-free and reliable energy supply to consumers. To achieve this goal, it is necessary to assess the level of energy security of the fuel and energy complex (FEC) of the country. For these purposes, it is proposed to form a model of the energy system that would take into account the peculiarities of all process flows that take place in it. For this purpose, we conducted a review of Russian and foreign studies in the field of modeling of the FEC in the course of the work. The main result presented in the article is a methodology for the building of a unified model of the fuel and energy complex to assess the level of energy security.

Highlights

We analyze the strengths and weaknesses of the models and lay the foundation to form a methodology for modeling the fuel and energy complex; We present a methodology for forming a multi-node model with a wide variety of primary energy resources, including renewable energy and water systems, as well as secondary energy resources, including cold energy
In connection with the above, the purpose of further work is to form a new methodology for creating a model of the fuel and energy complex to assess the level of energy security while taking into account current trends in energy industry development, based on the accumulated experience in modeling the FEC
The approach to modeling modern energy sectors proposed in the study will enable a higher quality of research into energy security if compared against its current level

Summary

Review

Most foreign studies lack "the fuel and energy complex" concept. Instead, the authors consider diverse variations of integrated energy systems (IES). Models have been developed since 1980 and there are currently three main modifications, which will be described in detail These models that include "Nadezhnost' TEK" (Reliability of the fuel and energy complex), "Rezerv" (Redundancy), and "REKS" (Development of the fuel and energy complex with energy security factored in) are based on a system of linear balance equations with a given constraint matrix. A number of simplifications were adopted, allowing for the minimum level of detail necessary to account for the two main systemically important factors: interchangeability of fuel and energy resources and territorial and transport links Such simplifications may include the lack of consideration of fuel transportation time, inaccuracies in the representation of technological relationships, the lack of consideration of the power balance, etc. [Inventories at the beginning of the period] + [production] + [input into the area] - [output from the area] - [consumption] - [Inventories at the end of the period] ≥ 0
