Steady state analysis and modeling of the gas metering and pressure reduction station using the electrical analogy

The existing interdependencies between electric power and natural gas networks are getting stronger with the increased penetration of renewable energy sources (RES) and should be considered at both the operational and the planning stage. A powerful simulation model based on an equivalent electrical model of the whole multi-energy system allows simultaneous analysis of these two connected networks in one simulation environment. In this study, the behavior of an ideal, as well as a real natural gas metering and pressure reduction station (MRS), has been analyzed and electric analogy steady state models (i.e. models with electric circuit elements) are given. The verification of the presented model is obtained by 24 examples carried out to cover a wide range of input data, and the simulation results are compared with the results obtained by SIMONE – the commercial software package for gas network simulation that is widely used in Europe. The results have shown a very high precision of the presented model and confirmed the proposed modeling principles, as well as the approach to modeling gas network elements in the electrical analogy.
