With the deepening of power reform, various market players want to understand the economic distribution of power grid intuitively and meticulously. In order to accurately and quantitatively analyze the profitability of each part in power grid, calculation method for profit distribution of steady-state power grid based on bi-directional power flow tracing is presented. Firstly, based on the power component theory and branch equivalent transformation, a bi-directional power flow tracing method suitable for any network is proposed. This method could provide the power-supply networks and the load-absorption networks, which are the physical basis for profit calculation. Then, based on the principle of cost conservation, the results of the bi-directional power flow tracing method are applied to the economic accounting. Economic distribution models are established, thus the profit distribution could be calculated. The effectiveness of the method and profit distribution solution is verified based on the IEEE 39 bus system and the benchmarking electricity prices in Beijing.
