Abstract
With the development of energy technologies, the electricity, cooling, heat, natural gas and other energy sources are tightly linked to improve the overall efficiency of energy system in integrated energy systems (IES). As the basis of optimization and simulation, the standardized modeling method of IES has become a challenge considering the deeply coupling of multi-energy resources. This paper proposes an energy bus structure that could realize the systematic modeling of IES. By adopting energy bus model, the components and the structure of IES can be mathematically presented. Then the matrix-based modeling method is proposed to describe the topology of the IES and the characteristics of energy converters. The equations that describe the energy flow relationship of the entire system can be listed out. Finally, a case study of Northern Customer Service Center (NCSC) of State Grid Corporation of China is conducted to verify the effectiveness of the proposed method.
