Key Techniques of Multi-Energy Systems Modeling and Simulation

The paper recaps the key techniques of Multi-Energy System (MES). As an option solution for renewable energy penetration, a MES combined with various types of energy carriers and services. The paper classifies the MES by different criteria. In addition, the author summarizes the techniques involved in the MES. Then, this paper discusses both steady state and dynamic models of all kinds of techniques in MES. It points out that the complex long-term dynamic modeling and multi-mode hybrid simulation should be considered in the dynamic analysis. A small MES case studies the dynamic simulation considering the proposed techniques. In conclusion, because of the mixing of multiple energy sources, the change of various kinds of working quality, and the superposition of different dynamic response time systems, the key of integrated energy system simulation (especially dynamic process simulation) lies in perfecting the modeling methods of coupling in physical levels and solution algorithms.
