Analysis of Fuel Flow and Pollution Flow Based on The Energy Tracing Results of Power Grid Source-flow

In addition to the traditional transmission and exchange of electric energy, the power network also indirectly plays a role in the transmission and distribution of fuel flow and pollution flow. Therefore, how to correctly calculate the energy consumption and the invisible distribution of pollutants in a power system has become an urgent problem. This paper proposes a method used for fuel flow and pollution flow analysis based on the energy tracing results of power grid source-flow. According to the energy flow information provided by the new source-flow electrical relationship analysis method, this paper is organized as follows. 1) The trend of fuel flow and pollution flow is analyzed for specific thermal power based on energy flow information; 2) The source of fuel flow and pollution flow is analyzed for specific load (user) based on energy flow information; 3) Fuel flow and pollution flow are analyzed for specific path (branch) based on energy flow component information. The results of case analysis and method comparison show that the method in this paper can calculate the distribution information of fuel flow and pollution flow in AC power network conveniently and correctly. And this method has positive significance for the scientific design and optimal operation of power market.
