Abstract: Due to the Deregulation of electricity industry, the competition is growing day by day between the Generators as well as in Distributors. But due to the competition in electricity market, it may cause congestion in the transmission lines and can cause black out in any area. This will affect not only the generation of electricity but also the consumers. To avoid this problem, in competitive electricity market it is very necessary to post the available transfer capability of a transmission network online, so that everyone can excess it and the congestion can be avoided. In this paper DC Power flow and power transfer distribution factors are used to calculate the available transfer capability of the network. The method used in this paper can be used for multiple as well as single transactions. In this paper some transactions are chosen and available transfer capability for both intact and contingency cases are calculated. The above said methodology is applied on IEEE 30-bus test system.
