The future of transmission - Switching to silicon
IEEE Power Engineering Review, 1989Reprinted from the EPRI Journal, June 1989. Economic and social forces, in addition to the technological developments discussed here, will help shape transmission systems of the future. Increased competition in the utility industry, for example, may bring fundamental changes to the U.S.

Tunable Nonlinear Transmission Lines with switched varactors
2009 IEEE International Symposium on Circuits and Systems, 2009Nonlinear Transmission Lines (NLTLs) have been used in many applications for waveform shaping and impedance engineering. To minimize insertion loss and jitter, adaptive impedance is desirable. Here we propose to use switched varactors on NLTL to achieve impedance-tuning.

Robust optimal power flow with transmission switching
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017To deal with the increasing penetration of uncertainties caused by renewable generations and uncertain loads, this paper proposes a novel robust optimization model for the optimal power flow (OPF) problem of power systems. In the model proposed, the generation and the network topology are co-optimized, and then the proposed robust optimal power flow ...

A genetic algorithm for AC optimal transmission switching
Proceedings of the Genetic and Evolutionary Computation Conference, 2021Optimal transmission switching (OTS) is a new practice in power systems and can improve the economics of electric power systems integrated with renewable resources such as wind. In OTS modeling binary decision variables are added to the optimal power flow (OPF) problem to represent on and off switching status of lines.

Flexible Transmission in the Smart Grid: Optimal Transmission Switching
2011There is currently a national push to create a smarter, more flexible electrical grid. Traditionally, network branches (transmission lines and transformers) in the electrical grid have been modeled as fixed assets in the short run, except during times of forced outages or maintenance. This traditional view does not permit reconfiguration of the network

Primal and dual bounds for Optimal Transmission Switching
2014 Power Systems Computation Conference, 2014It has been suggested that Optimal Transmission Switching (OTS) may reduce generator dispatch costs by as much as 10%, saving millions of dollars annually. However, this conclusion has been deduced primarily from studies using the DC power flow approximation on two power networks derived from the IEEE 118-bus and RTS-96 cases.

The integration of SONET into switching equipment: the merger of transmission and switching
IEEE International Conference on Communications, World Prosperity Through Communications, 2003The concept of integrated transmission and switching equipment using a SONET interface is reviewed. Advantages of integration and some of the generic applications of SONET in interoffice trunking are discussed. The author states that by directly integrating the SONET terminal into switching equipment, the operating company can save floor space, cabling,

Congestion Management Using Optimal Transmission Switching
IEEE Systems Journal, 2018In this paper, a multiobjective-based congestion management (CM) methodology is proposed using the optimal transmission switching (OTS) strategies considering the minimization of the total operating cost and the maximization of probabilistic reliability as two conflicting objectives.
