Power system Deregulation, bilateral/multilateral transactions, Static and dynamic constraints, Total Transfer Capability (TTC).
Recent blackouts in the United States and many other parts of the world provided a growing evidence that certain actions are urgently needed to ensure that the power system always remains secure, in permitting maximum power transactions over interconnected power system. Therefore the need for estimation of Available transfer Capability (ATC) is very important in deregulated power market as the correct estimation of ATC yields economically efficient operation of the restructured power system. This paper presents formulation of a set of AC distribution factors for Static ATC determination and assesses the security of the power system to reliably transfer bulk amount of power bilaterally and multilaterally over the interconnected transmission network from one area/region to another. These set of distribution factors are derived from AC load flow results and are used to check whether any of the lines flow (MW) limits and bus voltage magnitude (Volt) limits are not violated. The solution algorithm is tested on IEEE 6- Bus system and IEEE 30-Bus system to assess the ATC.
