Abstract
Aggravation of energy shortage and global warming has raised public low-carbon awareness and promoted the development of integrated energy system (IES). However, there has not been a general method for analysis of carbon emission distribution in the IES yet. A methodology combining energy flow (EF) with carbon emission flow (CEF) is proposed in this paper to calculate and analyze the carbon emission from the IES, which is composed of AC/DC power systems and heating/cooling systems. Decoupling methods are used to improve computing efficiency with good convergence in solving energy flow equations of subsystems. A typical case is modeled and simulated using CloudPSS-IESLab platform, a high-efficient power flow solver, with calculation results and Sankey diagram demonstrating the CEF distribution in the IES.
