A Non Proportional Sharing Power Flow Tracing Based on Bus Power Balance Equations

Using proportional sharing assumption in power flow tracing has always been a controversial issue because there is no proof to accept or deny such an assumption. In this paper, we propose tow new method one based on proportional sharing and the other based on bus power equations and network\'s impedance matrix to solve power flow tracing problems.And we use these solutions to find generation units and consumer loads shares in transmitting power of each line of the network. Both methods are able to handle loop flow and can be applied for both active and reactive power flow tracing. The case study on IEEE 24 bus reliability test system (RTS) shows that the proposed tracing methods are effective and accurate in transmission cost allocation and other tracing problems. Also a comparison between these methods has been made to illustrate the efficiency of proportional sharing assumption.
