The electrical analogy model of the gas pressure reducing and metering station

To overcome balancing challenges in the power system, when existing balancing capacities are not sufficient, one of the most used solutions is the installation of new gas-fired power plants, and, nowadays, power-to-gas facilities. Consequently, the power and natural gas systems are getting so linked and operationally interdependent that they must be simultaneously analyzed in an integrated way. To do so, it is useful to have a robust iterative-free simulation model based on the electrical analogy. Hence, the electrical equivalent models of an ideal as well of a real natural gas pressure reducing and metering stations (GPRMS) in steady-state are presented in this paper. For verification, two case studies were conducted. In the first case study, a comparison was made between the results of 24 simulations performed by the presented models and well-known commercial software for natural gas network analyses - SIMONE. The results indicate a very good agreement. In the second case study, 11 measurements from the real GPRMS have been used to determine the most crucial parameter in a real gas pressure reducing process. Both case studies have confirmed a very high precision of the presented real GPRMS model, and the correctness of the modeling approach applied. (C) 2020 Elsevier Ltd. All rights reserved.
