Research on modeling and simulation optimization of multi-energy station based on TRNSYS

With the continuous growth of global energy demand and the increasingly severe environmental problems, multi-energy stations, as a comprehensive energy system integrating a variety of distributed energy forms, have gradually become an important way to achieve low-carbon energy transition. This paper focuses on a typical multi-energy station, constructs its dynamic simulation model based on TRNSYS software, and deeply analyzes the operating performance of the system. Through the simulation analysis of different operation scenarios, the research results show that the interconnected operation of energy stations can significantly save $32.8 \%$ of energy consumption compared with independent operation, and this benefit is mainly due to the staggered characteristics of heat load. The study provides an important theoretical basis for regional energy management and emphasizes the necessity of implementing energy station interconnection according to local conditions to improve energy efficiency and promote the wide application of clean heating.
