Allocation of transmission losses and network charges for cross border trades in ASEAN power grid based on tracing methodology

In this paper, a unified transmission pricing based on electricity tracing methodology of cross border trades among the Association of South East Asian Nations (ASEAN) members is proposed. The use-of-system charges comprise a charge of the transmission capacity usage and a charge of transmission losses in the interconnection system. To demonstrate its effectiveness, the proposed methodology is harmonizedly applied to cross border trades among the ten member countries of ASEAN Power Grid. Test results indicate that the proposed methodology could recover the investment cost and operation and maintenance costs in a simple, transparent, and less-time consuming manner.
