Abstract
In order to decarbonize the energy sector, the interdependencies between the power and natural gas systems are going to be much stronger in the next period. Thus, it is necessary to have a powerful simulation model that is able to efficiently and simultaneously solve all coupled energy carriers in a single simulation environment in only one simulation step. As an answer to the described computational challenges, a unique model for the steady-state analysis of a multi-energy system (MES) using the electrical analogy approach is developed. Detailed electrical equivalent models, developed using the network port theory and the load flow method formulation, of the most important natural gas network elements, as well as of the linking facilities between the power and natural gas systems, are given. The presented models were loaded up into a well-known software for the power system simulation—NEPLAN. In the case studies, the accuracy of the presented models is confirmed by the comparison of the simulation results with the results obtained by SIMONE—a well-known software for natural gas network simulations. Moreover, the applicability of the presented unique model is demonstrated by the MES security of a supply analysis.
Highlights
The main goal of actual energy policies is the decarbonization of the energy sector in the medium to long term [1,2,3]
The overall multi-energy system could be simultaneously solved as one electrical network and in one simulation step, i.e., without high resource-consuming iterative inter-model calculations associated with the separate network modeling approach
The developed models of network elements were used for modeling multi-energy system (MES) in the electrical software package—NEPLAN
Summary
The main goal of actual energy policies is the decarbonization of the energy sector in the medium to long term [1,2,3]. The main issues of all cited papers, as well as other papers dealing with the MES modeling, have been the complexity of modeling and slow computational performance The former is a result of the applied modeling approach where every energy system is modeled separately and linked through the consumption and constraints equations [24,25,26]. The separate modeling of the coupled energy carrier infrastructures was subject in [28,29,30] In these papers, unlike the above-referenced papers, MES is analyzed simultaneously by using the Newton–Raphson approach, which has several significant limitations. The electrical analogy approach is applied in MES modeling that is consisted of the integrated power and natural gas systems.
