Fast service restoration under deregulated environment

The power quality service has been considered to boost the competition in the distribution side, which is necessary to meet the customers' demands in the near future. Due to increasing demands for the high reliability, the fast service restoration has been a hot issue with the fault tolerable distribution system. In order to ensure high reliability, the scope of service restoration should be extended to severer faults such as multi-feeder outages, bus outages and transformer outages at the substation, and out-of-services of a whole substation. In this panel session, the fast service restoration is discussed with the necessity of developing new approaches to be adapted to the distribution system under deregulation, mainly focusing on fast solution search algorithms, multi-switching strategies for severer fault occurrence, search for the fault section, and fast power flow calculation.
