Transmission power loss has become a progressing issue these days due to the changes from monopolized to deregulation environment. This can be due to the large transmission power loss which leads to monetary losses. The presence of deregulated power system requires the participants to make decision on transmission line charge. Hence it is necessary to have a method to determine fair, transparent and equitable charges among market participants respectively. This paper proposed a heuristic technique termed as Artificial Bee Colony (ABC) algorithm for real power line allocation for solving the line loss allocation among market participants. In this study ABC Algorithm optimization engine is utilized to solve the real power loss allocation. The proposed technique was validated on IEEE 30 Bus Reliability Test System. Results obtained from the study indicated that the proposed ABC algorithm technique is superior as compared to Particle Swarm Optimization (PSO) technique.
