Abstract:- This paper presents different flow-based transmission cost allocation (TCA) schemes for distributing the transmission usage costs to system individuals. Different independent system operator (ISO) visions are suggested using the proportional rata method. In addition to the suggested schemes, three other approaches are proposed. The first proposed approach generalizes the equivalent bilateral exchanges (EBE) concepts presented in [2] for lossy networks through multi-stage procedure. The second proposed approach is based on modified sensitivity factors (MSF). These MSF factors are developed from the actual measurements of power flows in transmission lines and the power injections at different buses. The proposed approaches exhibit desirable apportioning properties and are easy to implement and understand. Case studies based two test systems 5-bus test system and the IEEE 14-bus test systems are carried out to show the proposal's capability for flow-based TCA schemes.
