Available Transfer Capability Determination Using Linear Sensitivity Based PTDF Method in Restructuring Power System

The demand of electricity is continuously increases day by day in today’s market scenario and complexity arises all over the world due to huge population and modernization in developing countries. To meet the rapidly increasing demand and for the reliable operation we support private participation to generate the electricity. In the last few years the concept of deregulated market is more useful instead of regulated. Thus government has invited the private sectors into the power generation, transmission and distribution by fixing some certain rules over it called as restructuring power system. Having present of so many private participates congestion should be there. This type of competition in the power industry, there has been a search for the better utilization of the transmission facilities. In this contest Available Transfer Capability (ATC) indicates how much inter area power transfers can be increased without change in system security must be considered. Thus ATC calculation gives us an important indication of relative system security and reliability.
