Backtracking Search Method for the Optimal Restoration of Distribution System during Cold Load Pickup
نویسندگان
چکیده
Restoration of distribution system in cold weather and after long interruptions creates cold load pickup problem due to loss of diversity among the loads in residential area. Under such conditions the distribution system load may have to be restored step by step, using sectionalizing switches to prevent overheating of substation transformer. The order in which the sections are restored has a significant impact on the total time of restoration. In this paper, an order of sections will be selected either to minimize the total restoration time or to minimize customer interruption duration. Results obtained using Backtracking Search Method (BTSM) is compared with Adjacent Pairwise Interchange Method (APIM) and global search for a test system. Key-Words: Distribution system restoration, cold load pickup, step by step restoration.

متن کاملSmart load shedding and distributed generation resources rescheduling to improve distribution system restoration performance
After a permanent fault occurs if it is not possible to supply the load in the network, the optimal load restoration scheme allows the system to restoration the load with the lowest exit cost, the lowest load interruption, and in the shortest possible time. This article introduces a new design called Smart Load Shedding, abbreviated SLS. In the proposed SLS scheme, the types of devices in smart...

متن کاملDistribution System Restoration after Prolonged Outages
Most of the customer outages are the results of some problems related to distribution systems. Prolonged outages may cause cold load pickup problems because of the increased penetration of thermostaticallycontrolled devices and the loss of diversity among these devices. Since loads higher than normal may be expected after prolonged outages, restoration problems may occur when there is not enoug...
