【Title】Bi-directional Tracing Method Based on the Separation of Power Supply Paths
【Abstract】With the deepening of electric power system reform, accurate physical basis is urgently needed for the research on economic problems, and power flow provides theoretical foundation for the fair and public operation of power market. But most existing tracing methods are based on proportional sharing principle which is difficult to be proved strictly. And the operation parameters of power system change with the states of system, while the intrinsic parameters of power system, such as line impedances ， and the network structures are fixed. This paper presents a bi-directional tracing method based on the separation of power supply paths in power grid. Under the premise of known power flow in an AC section and in consideration of the line-to-ground capacitances, this method conducts an equivalent conversion on the system’s intrinsic parameters, which cannot merely form the single-power multi-load networks, the single-power single-load networks and the single-load multi-power networks, and can further realize the bi-directional tracing in multi-power multi-load loop networks. Coordinate this method with economic accounting, the profit distribution of the power grid can be computed and revealed.
