A Power Flow Tracing Method Based on the Circuit Analysis of Power Supply Path

According to the problems of the present power flow tracing methods, this paper proposes the concept of power supply path of source and a new flow tracing method based on the circuit analysis of the power supply path under the constraints of all the basic electrical laws. This method makes the research on power flow tracing is not confined to only consider the numerical decomposition of power flow, but gives out the power transfer relation between arbitrary two branches for further so that we could discover the power transmission mechanism in the steady state of the power grids deeply.
