Abstract :
Transmission pricing has become one of the important issues of the power industry with the power industry´s restructuring. The pricing should be done fairly to achieve a healthy competitive environment. The load tracking method will be discussed in this paper. For this purpose, various operating points were made around the nominal operating point at first, using statistical data. After that, the network load flow is being calculated for each operating point and the linear regression and correlation coefficients between each producer/consumer’s generation/consumption and the following power of each line, were being achieved and the players' share of the transmission cost is being calculated by combining this coefficients. The participation coefficients were being calculated at the end for the 39 Bus IEEE test system and its results will be compared with previous methods. The Comparison of the results show that the reviewed methods cover the transmission costs, but the determined share for each player using this paper’s method, has a greater proportion with the amount of the transmission network usage.
