Abstract

Abstract:

Integrated energy system (IES) is an important development direction of energy consumption in the future, and will play an increasingly important role in improving the energy efficiency of integrated energy use and the consumption of renewable energy. However, due to the high coupling of energy system in IES and the uncertainty in each link of source-network-load-storage, the dynamic process of IES is extremely complex, which brings great challenges to the optimal operation of IES. This paper aims at the optimal operation of IES. Firstly, the concept of IES is introduced and its main characteristics are analyzed. Secondly, the research status in home and abroad on the basic information perception of IES operation, the dynamic coordinated optimization scheduling system with hybrid time scales and its solution algorithm are summarized, and the shortcomings of the existing research are pointed out. Finally, the future research direction is prospected. The results of this paper will provide a reference for the follow-up research of integrated energy system.

Key words: integrated energy system (IES), optimal operation, information perception, hybrid time scales
