Abstract: Interconnection and environmental friendliness are important characteristics of regional energy system and inherent requirements for its low-carbon economic operation. Research has made some progress in system design and planning,simulation modeling and optimized dispatch,but less attention has been paid to environmental benefits from the perspective of openness. According to the practice of existing new energy micro-grid projects,this paper studies the correlation between market transaction and regional energy system,and introduces a method for constructing a carbonneutrality management information system under linkage mechanism of multi-markets. This paper also gives the illustration for analyzing implementation process of low-carbon route under specific situations,which shows the green,low-carbon,collaborative and open characteristics of the carbon-neutralization management information system.
