A Carbon Emission Flow Analysis Model and Method of Active Distribution System Based on Power Flow Tracing

Under the dual pressure of energy and environment, low carbon of power system has become the focus of current research. It is a basic work to calculate the carbon emission of power system scientifically and accurately. A carbon emission analysis model and method for distribution system with distributed generations is proposed in this paper based on the theory of power system carbon emission flow. Firstly, the deep correspondence between current and carbon flow is found that is named carbon flow density. Then, the carbon flow density is used as a bridge to establish the carbon emission analysis model of the distribution systems with distributed generations which combined with the perfect system power flow theory and considered the network loss and high proportion of distributed generations. Finally, the effectiveness and practicability of the method are verified by IEEE-33 node system.
