Modified Methodology for Tracing Power Flow

Due to continuing trend towards deregulation and unbundling of transmission services, usage allocation has become critical. It is important to determine load being supplied from a particular generator. We need to know in a transmission line, the proportion of power going to a given load and the loads contribution to overall system losses. Thus, tracing method is used to trace the flow of electricity in a meshed electrical network. In this paper a modified methodology is proposed for tracing reactive power flow without adding fictitious nodes on system lines. Also, in this paper a modified methodology is proposed to break down the total real and reactive power loss in a transmission line into components to be allocated to individual loads.
