Optimal Transmission Switching With Contingency Analysis

IEEE Transactions on Power Systems, 2009
In this paper, we analyze the N-1 reliable DC optimal dispatch with transmission switching. The model is a mixed integer program (MIP) with binary variables representing the state of the transmission element (line or transformer) and the model can be used for planning and/or operations.

Transmission Switching in Expansion Planning

IEEE Transactions on Power Systems, 2010
Transmission switching (TS) is introduced to add flexibility to the transmission and generation capacity expansion planning problem. TS could improve the performance of the capacity expansion planning model and reduce the total planning cost. The capacity expansion planning problem is decomposed into a master problem and two subproblems.

Static Switching Security in Multi-Period Transmission Switching

IEEE Transactions on Power Systems, 2012
Transmission switching can improve the economic benefits of a power system through changing its topology during operations. However, the switching operation itself represents a step change in power systems, which is, to some extent, similar to a contingency that can bring disturbances into systems.

Petabit Class Transmission and Switching

2020 European Conference on Optical Communications (ECOC), 2020
We evaluate the requirements for future spatial-division multiplexing networks operating at throughput higher than 1 Pb/s and discuss possible solutions to support ultra-high capacity.

Design of Switched Capacitor Filter with Transmission Gate Switches

SSRN Electronic Journal, 2021
A filter is a circuit that allows some frequencies to pass through it, while attenuating others frequencies. Generally, Filter can be designed using components like resistors and capacitors. In VLSI Technology Resistors with large values cannot be inserted on to a chip so easily. An alternate circuit can be replaced in place of resistor (i.e., Switched

Transmission of double-impurity atomic switches

Physical Review B, 1996
The electron transmission properties of a molecular-electronic switch, represented by a monatomic chain with two atomic impurities, is studied via the tight-binding model. A method, based on the Lippmann-Schwinger equation, is used to obtain simple expressions for the transmission probability.

The Maximum Transmission Switching Flow Problem

Proceedings of the Ninth International Conference on Future Energy Systems, 2018
The Maximum Transmission Switching Flow (MTSF) is the problem of maximizing the power flow of a power grid by switching off lines. This static transmission design problem is known to be NP-hard even on strongly restricted graph classes. In this paper, we study the combinatorial structure of the MTSF problem and its relationship to familiar problems. We

Exploiting Symmetry in Transmission Lines for Transmission Switching

IEEE Transactions on Power Systems, 2012
Symmetry caused by the presence of identical transmission lines in the transmission switching problem can have a significant negative impact on mixed-integer linear programming methods due to the redundant computation of identical subproblems. Unfortunately, it is not obvious how to remove symmetry by remodeling pairs of identical lines as one line ...

Transmission Switching Characteristics of PLZT Shutters

Applied Optics, 1973
The ON-OFF ratio, insertion loss, and switching speed of polycrystalline ferroelectric ceramic PLZT electrooptic shutters fabricated with a zirconium to titanium ratio of 65 to 35 and a lanthanum concentration of approximately 8% were investigated as functions of voltage amplitude and duration. Larger ON-OFF ratios (33 dB for dc mode) were observed for
