Abstract
For technical, economic and political reasons the volumes of Russian pipeline gas export can be considerably reduced for relatively short periods of time. Such situations create unconsumed gas volumes in the gas transmission network of Russia, which can cause mal-function of the network. Here a problem arises of how to fast and optimally distribute the un-consumed gas to minimize various negative consequences. The paper presents a method for solving this problem. A focus is made on a model necessary to perform calculations within the proposed method. A situation of a short-term disruption of Russian gas delivery to European consumers through the territory of Ukraine is modelled, with an analysis of potential consequences and actions necessary to prevent them.
Highlights
Russia is one of the largest gas producers and exporters
To solve the problem of unconsumed surplus gas in the unified gas supply system we propose changing the operation mode of the underground gas storage (UGS) facilities
Since the base model for the determination of maximum flow of minimum cost [20] does not allow us to do that, we present its modification implemented in the software “Russia’s Oil and Gas”: (3)
Summary
Russia is one of the largest gas producers and exporters. Russian natural gas is exported to European and Asian gas markets. The accumulation of unconsumed gas in the gas transmission network can upset the balance between gas production and consumption, and lead to a pressure increase in considerable part of worn-out gas pipelines, and emergency situations All these factors will negatively affect the operation of Russia’s gas industry. The Energy Systems Institute SB RAS applies the software “Russia’s Oil and Gas” [18] to study the issues of survivability and reliable operation of energy systems This software makes it possible to determine the extent to which the domestic and export demand for gas is met, when various types of emergency situations occur. The model of flow distribution in the unified gas supply system is embedded in the software “Russia’s Oil and Gas” It is intended for the assessment of transmission capacity of the unified gas supply system under various types of disturbances. In [20] presented results of research of possible implications for European energy from violating the Russian gas supply through Ukraine, by using following software “Russia’s Oil and Gas”
