Determination of Optimal Transmission Lines Switching for Power System Restoration

The set of activities, which are taken to return a power system to the normal stage after partial of complete blackout, is called power system restoration. It is the process of restoring power plants, re-energizing transmission lines and restoring customer loads. This process should be conducted as rapidly as possible without causing any failure or damaging to any equipment. In planning of power system restoration, one of the most important steps is to determine optimal switching of transmission lines. In this paper, a method for reaching the shortest path possible between system buses while achieving the minimum time of switching during restoration is presented. To ensure that the results are applicable, a bus voltage assessment and path load capability checking are considered. The results of the program for the IEEE 39 bus and Iran southeast power systems are presented in this paper.
