doi:10.16183/j.cnki.jsjtu.2023.461

Abstract

Abstract:

Due to the complexity of equipment components in integrated energy systems, which involve multiple forms of energy such as electricity, gas, heat, and cooling, a massive amount of heterogeneous data is generated during interconnection and transmission processes, making it difficult to effectively reflect the characteristics of integrated energy systems. In light of this, basic units of integrated energy system are adopted as the research foundation in this paper. First, typical basic unit devices of integrated energy systems are carefully selected based on statistical clustering analysis, whose characteristic data are extracted to represent the basic unit features. Then, models of basic unit in integrated energy systems are established based on their energy and quality attributes. Finally, the rationality and applicability of the proposed models for various types of basic units in integrated energy systems are validated by case studies.

Key words: integrated energy system (IES), basic units, statistical synthesis method, fuzzy clustering, load modeling
