Peak underground gas storage efficiency in reducing the vulnerability of gas supply to consumers in an extensive gas transmission system
The paper seeks to address the questions of how to assess the comparative efficiency of peak underground gas storages (PUGSs) to reduce the vulnerability of regional gas systems in the case of emergencies in the gas industry and how to prioritize the commissioning of these PUGSs in a large-scale geographically distributed and ramified gas transmission network. The research method used to answer the posed questions involves the analysis of the natural gas consumption in regions, the technological structure of the main gas transmission network serving these regions, and the technological characteristics of PUGSs planned for construction. This research method suggests specialized multi-iteration model studies to adequately simulate the operation of all process objects of the gas transmission network. Emergencies in the gas transmission network are simulated through the failure of the critical facilities of this network. The operation of the gas transmission network under these conditions is simulated with the planned PUGSs introduced into the network (one at a time). Comparative efficiency and priority of each PUGS are determined by a relative decrease in gas shortage for consumers in the case of this PUGS commissioning during large-scale emergencies in the gas transmission network. The main research results are illustrated by the case of Russia that has a developed gas transmission system with a complex configuration and considerable amounts of gas transported. The vulnerability analysis results are presented for regional gas systems located in the operating area of the Russian gas transmission network before and after the commissioning of these PUGS facilities. All planned storage facilities are ranked according to their efficiency and priority for reducing the vulnerability of regional gas supply systems in cases of large-scale emergencies in the country's gas transmission system. The findings suggest that the proposed approach, when applied to Russia, will reduce the average expected gas shortage across the country under the grave emergencies in the gas transmission network by up to 27%. The conclusion based on the studies and obtained results indicates that the proposed approach is feasible and effective. In practical terms, for Russia, it has been inferred that it is necessary to investigate the possibilities of additional PUGSs in the northern part of the Russian gas transmission network. This will additionally decrease the vulnerability of gas systems in Russia's northern areas, which are most susceptible to gas shortages under emergencies in the gas industry. © 2022 Elsevier Ltd
