Abstract:

Integrated energy system (IES) has become the research hotspot of the energy system due to the characteristics of multi-energy joint coordination and energy efficiency. Because of the complex structure, control, and fault characteristics of IES, it is difficult for traditional protection principles and schemes to adapt to system requirements. This paper first analyzes the structural characteristics and control characteristics of IES, and studies the fault characteristics of the core power part based on its characteristics. Then, based on the fault characteristics used in the existing protection principles, it classifies and analyzes domestic and foreign research, improvement status, and protection applicability. Finally, it discusses and prospects the research and development direction of IES line protection principles and schemes.

Key words: integrated energy system (IES), structure feature, fault feature analysis, protection principle, applicability analysis
