The Impact of Grid Uncertainties on Optimal Transmission Switching

2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019
Optimal transmission switching is proposed to reduce transmission congestion and optimize the system operational cost. Such switching decisions are usually determined in the day-ahead stage. However, the load and renewable generation forecasts may have significant deviations from the actual values in the next day.

Promises of conic relaxations in optimal transmission switching of power systems

2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
This paper studies the problem of optimal transmission switching (OTS) for power systems. The goal is to identify a topology of the power grid that minimizes the cost of the system operation while satisfying the physical and operational constraints. Most of the existing methods are based on converting the OTS problem into a mixed-integer linear program

Optimal transmission line switching incorporating dynamic line ratings

2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2017
Real-time ampacities of overhead transmission lines vary in time with the actual operation conditions. Therefore, the security margin of power system operation can be reduced when the dynamic line rating (DLR) is considered. In this paper, the model of homogeneous dispatch with transmission switching is proposed to take into account dynamic line ...
