Energy-efficient control of underground gas storage

Abstract

PURPOSE: The work devoted to the development of the system of effective dispatching control of the process of operation of underground gas storage facilities. This method connects the parameters of the filtration processes in the reservoirs (with concentrated sources) with the parameters of the discrete-continuous processes that take place in multi-shop compressor stations.

DESIGN/METHODOLOGY/APPROACH: The authors formulated the necessary direct and inverse problems for planning the operating modes of the UGS according to effective optimality criteria. To solve them, they developed fast-converging methods and algorithms of minimal complexity, in particular, they applied/developed combinatorial optimization methods for forming optimal operational and predictive operation modes of UGS. This made it possible to achieve the necessary level of efficiency in decisionmaking by dispatch services. The authors paid special attention to the developed methods of solving problems of flow analysis in a network-type system with various boundary conditions.

FINDINGS: The APC was funded by AGH University of Krakow.

PRACTICAL IMPLICATIONS: This approach made it possible to combine various models of processes of different physical nature into a single thermo-hydraulic complex. The article provides examples of solving problems of analysis and planning of UGS operating modes. The qualitative and quantitative characteristics of the developed and tested mathematical models in the real conditions of its operation are described.

ORIGINALITY/VALUE: The article presents methods and tools for the effective management of underground gas storage facilities.
