Güç sistemleri, elektrik enerjisinin kesintisiz bir şekilde tüketiciye ulaştırılmasını sağlayan ve birbiriyle koordineli çalıştırılan ekipmanların toplamı şeklinde ifade edilen kompleks yapılardır. Ancak bazı durumlarda güç sisteminde tam ya da kısmi olarak sistem çökmesi meydana gelebilmektedir. Bu bazen hemen giderilebilirken de giderilmesi uzun sürmektedir. Uzun süren kesintiler sonrasında t...

Original scientific paper After large scale blackout, there may be more than one black-start unit in power system. A rational subsystem partitioning restoration scheme could speed up the entire system restoration procedure and promote restoration reliability. In the paper, a subsystem partitioning strategy considering the restoration reliability is proposed. The calculation of nodes restoration...

This paper studies the restoration of a transmission system after a significant disruption (e.g., a natural disaster). It considers the co-optimization of repairs, load pickups, and generation dispatch to produce a sequencing of the repairs that minimizes the size of the blackout over time. The core of this process is a Restoration Ordering Problem (ROP), a non-convex mixed-integer nonlinear pr...

After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units.  In order to solve this problem, this paper provides a restoration s...

Smart grid has been introduced to address power distribution system challenges. In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called the outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will...
