Research on carbon emission flow in power system based on carbon flow tracking

Abstract:
The use of carbon flow tracking technology that shifts the carbon emission problem from the power generation side to the whole process of power transmission has certain practical significance. Carbon flow, a virtual network flow that exists depending on the tidal current, can measure the carbon emission intensity of the load and the carbon emission generated by the network loss on the basis of the deterministic tidal current. It provides a basis for the division of emission reduction responsibilities on the user side, and provides a reference for low-carbon power dispatching and power demand side management. Based on the principle of complex proportional sharing, a complex power flow tracking model is constructed, and the power supply ratio of each generator set in the load node and line is determined by the power flow tracking method. Then, a carbon flow tracking model is constructed based on the power flow tracking model, which incorporates the carbon flow information attached to the power flow into the entire network, and realizes the user-side carbon emission measurement.
